Ubuntu Networking :: Would Like To Optimize DSL Connection / Performance
Sep 3, 2010
My DSL is working and my computer is on line but I would like to optimize my connection for better speed. I found a utility for this at speedguide.net but it was written for Windows.
I'm looking for a newbie friendly guide on tuning stuff like TCP and whatnot. I installed a program on my sister's Windows computer called Internet Cyclone and it did all the settings itself, but I can't seem to find such a program for Linux. I kinda want to learn to do it myself too, so can you point me to a newbie friendly guide on how to optimize my Internet connection settings?
I have installed a linux server, centos gui server with Raid1, his role will be only a file server. I installed samba and configured it. The file system is EXT3. the server got 4 gigs of memory.There is a program in windows that writes files to the share.I searched and i found that there is some commands that you add and they boost the performance.
I got complains that the writes are not fast enough. Before me another IT guy configured the file server and it was faster, what he told my customer that he changed some command of cache but i dont know exactly what he did. I have been asked to find how to boost the performance.Please give me more commands to try to boost the performance of Samba or tell me if i need to change anything..
I just wanted to know if having my laptop set to ondemand, will this affect performance in any way? I realize it increases the clock speed to performance when the CPU is under load, but does the time it take to go from ondemand to performance affect speed? Will there be any noticeable difference between the two setups? I have a dual core intel at 2.2GHz when in performance. When ondemand is set with no load it downclocks to 800Mhz.
i didn't know where to post this so i decided on "General" section. I'm working with kind of an "old" computer, low HDD and graphics, but decent amount of RAM and good processor ( for an old computer, and it was bough for company use ) So i want to speed things up a bit, i don't mind waiting a bit longer when GIMP is loading, but FireFox is giving me issues, loads slower, and internet isn't as fast as its suppose to be, i started playing a game on facebook recently and it was fine, but lately it takes for ever to load and do things in it, i tweaked some options in it, and its better, but now when i click response time is slower ( altogether is quicker but still not enough ) Is there anything i can do?
I have the most recent version of Ubuntu, and I'd like to optimize it. I have 888MB RAM and an older celeron processor. Here are the only things I use on a daily basis:
I feel like there is a lot of extra stuff I could remove, but I don't want to just start removing random things that may break dependencies, etc. I want to do this b/c it seems like my desktop is sluggish most of the time.
I snagged the 10.10 alternate install ISO for PPC and got it up and running on a 1ghz G4 eMac with 1gb of RAM and a 60gb HDD. It runs... OK. It could be a lot better. I'm planning to shut off the bluetooth and CUPS services since neither apply to this system; are there any other services I can shut down, or any other tricks I could do to make it run a bit more smoothly?
What about alternate window managers? I realise that the PPC platform kinda limits me, but what about TWM or FVWM?
Unfortunately my ubuntu installation wakes 31 seconds to get to the boot screen, almost identical to my windows 7 partition. I've already configured grub to my needs, so reducing the counter has already been done, but I have no idea what else to do for my boot speeds when it comes to ubuntu. If anything I can live with these times, but it would be very nice to have it boot at lightning speeds I may even buy a SSD when I get the money.
Ubuntu V 10.10, vs Windows 2k server. Comparable hardware. From a XP workstation on the same gigabit switch. Share uses Samba.
I start a copy of a 2GB file from the workstation to my Linux share, and then to my W2k server. The copy to the w2k machine finishes in less than 60 seconds, the copy to my Linux machine takes 4 minutes. I am a windows veteran, but a Linux newbie. Are there settings I should look at, or something faster than Samba?
I am using ubuntu desktop edition to run My drupal website on Intranet. I know for running web servers best thing to install is ubuntu server editions, but due to some problem i am using Desktop edition.I installed XAMPP on my machine an my website is up and running. I want to know how can i optimize my machine?? Since I will not use very less features of desktop editions are there any things which I can remove or stop which will free memory and cpu consumption, are there any packages which i should install to increase the performance of my ubuntu??
I am finally coming around to selling my iMac G3s and eMac. I will reformat the drives in them and put on Puppy Linux for the iMacs and Xubuntu on the eMac. If I can, I will repair OS X on them all and will dual boot if possible. All of this will be done using the Intel iMac via Firewire. I would like to know if there is a way to make these machines any faster (without money) and "safer" so the next owner feels sure they won't be failing on them soon.
The PC is AMD Duron, 370 Mb memory, Hd Maxtor 80 Gb, S.O. 10:10 maverick Ubuntu, Linux Kernel 2.6.35-24-generic.
Gnome 2.32.0
Who can I analyze this screen:
Code:
In particular, what are all the mistakes, how much ram maximum support, what kind and where can I find the physical space for the three DIMMs that are missing in the list.
I need to optimize the implementation of DSR algo using NS-2. Now i need to identify the first of all "the parameters which i can change and which are effective in optimization point of view." I want to get into the c++ code as well as header files which are used to implement DSR algo.
I have a WinXP virtual box and have setup a Samba server to have it use directly a couple of directories on the Linux side. The Samba performance is definitely better than the built-in shared folders of the virtualbox, but there is nothing to write home about either: transfer seem to top at around 3Mbyte/sec.
The machine is a laptop (Core i5 CPU (M520@2.40GHz) and a 7200RPM HDD) running Kubuntu 10.04.The Samba share uses a dedicated "host-only" network adapter. There is an iptable-based firewall to which i added the required 4 statements to let the Netbios traffic go through (without them nothing works...)So, given the hardware, are the 3MB/s a decent figure? And if not, what should I aceeive, and where can I look improve on the current numbers?
Recently I was trying to use Gentoo, and I was really impressed of how it is faster than Ubuntu in running applications, specially when I build wine and was able to run Oblivion at a reasonable speed. I would like to know if there is a way to compile Ubuntu from source code, to optimize it to my hardware.
I installed Ubuntu 10.10 today Netbook Edition on the Asus Eee PC 1015PED. Specifications for Asus Eee PC 1015PED: Atom 455, 1.66 GHz, 1Gb ram, 250Gb drive, Bluetooth 3.0, 0.3 megapixel webcam, Gigabit Ethernet, WSVGA (1024x600), sound card compatible with the HD audio connector, d-dub, three USB 2.0 ports, 6-cell - lithium Ion - 4400mAh, WiFi 802.11 b/g/n.
solve the problem or an indication of the package to install. tutorial under the title, which services to disable to boost performance. first place to help you connect to the Internet. especially to the netbook'a - Asus Eee PC 1015PED. I updated everything on connection via cable. Detects the connection, but when it connects after a while.. "Wireless - Network Disconnected".
I would like to re-raise this topic that I have seen on other discussion boards but seems to be going no where.I have been using Ubuntu for many years now having switched from other distributions. All my machines ran some version of Ubuntu, until just recently. I upgraded my personal HP TX2500 from 9.04 to 10.04. No problems. After 10.10 had been out for a while I upgraded again. The wireless would drop when busy/(signal slightly weakened) etc. It would not function again unless the wifi module was reloaded.
Then I installed 10.10 on my HP NC6400 the same thing occured. I installed Ubuntu 10.04 instead. It seemed no better. After some Googling, it seemed I was not alone. I tried all the suggestions I could find and none of them worked. One suggestion was to install Fedora 14. This works perfectly on the nc6400. The HP TX2500 has been reinstalled back with 10.04 where the wireless seems ok and I assume I am stuck there for a while.
Now my question is why would the networking behave this way for Ubuntu 10.10 (10.04 as well on the NC6400) but wireless on Fedora 14 is perfect (I mean really good! Better than either Ubuntu 10.04 or 10.10 on any of my laptops) on the NC6400. I am hoping that we can find a way to fix this, otherwise I will likely have to drop Ubuntu completely because I do not have an upgrade path for laptops. There must be many other users in the same position who are not discussing it and just rebooting each time this occurs. This must give a negative perception of otherwise great software.
I installed a new PCI wireless card (Broadcom Corporation BCM4306 802.11b/g Wireless LAN) today I got it to work but, I am not getting the right download speeds before I was downloading at 700kb/s and 1mb/s but now its downloading at speeds like 200kb/s 250 being the highest I've seen it all night
Some more specs: 01:0a.0 Network controller [0280]: Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller [14e4:4320] (rev 02)
And I do have the Restricted driver installed and activated, also I was reading that restricted drivers slows performance, is that true?
I saw many people were talking about how to optimize apache and mysql here and also in other forums and blogs. I am currently hosting some sites and some IRCD processes (a tiny network)in a dedicated server with spec:
We got about 30,000 to 40,000 page views per day. I would like to ask people here about the opinion of apache and mysql optimization based on this server spec and current number of page view.
After having tried to fix the plymouth without any successfully result (i am meanning the thread i began few weeks ago and sited here: [URL]. I decided to keep nvidia's privates drives on giving up any hope to fix the plymouth bug and, right now, i would like to optimize or configurate the drivers properly like it is on Mandriva One 2010.
Perhaps someone is not exactly understand what i want to say. Well, i was using Mandriva One 2010 before installing Ubuntu Maverick and i have noticed there was no a low latency, lag effect, low performance or a lack of initial smooth and clean windows moves in Mandriva One 2010 but on Ubuntu there is.
This is very hard to explain for me, for example, If i use the "flip windows selector" (i mean, pressing "<Super>+Tab" keys) show me this effect too slow initially but if i forced the GPU for a while (repeating and pressing the keys), the lag effects vanished and then, the flip windows selector works nicely fast, clean and smooth. Now if i stop to use that effects, let the Nvidia GPU repose a while and use again the flip windows selector again, the lag effects come up again.
This fact does not just happen using the "flip windows selectos", any effects which minimize, resize or maxime the windows generate that annoying initial lag effects, for example, a simple minimize windows:
I am in despair with this, i do not if i have to do some change in the /etc/X11/xorg.conf file, what i have to configurate in the "Nvidia X server Settings" or in the "compiz manager settings" application.
Anyone knows a tutorial about how to optimize the Nvidia drivers on Ubuntu? or the Compiz effects to reduce the lag effets?
iwconfig shows that the bit rate is 130Mb/s and link quality is 98/100. I'm using the wcid network manager instead of defaul gnome one. I'm getting lots of packet loss and performance is very bad. The connection is practically unusable. I've tried installing the compat wireless backport package but that did not work at all.
I have fedora 12 and since I started using firefox I noticed that it performs very slow. Slow when opening, when displaying information etc..I thought that there was something wrong with my wireless device but I installed opera and it works very fast. The strange thing is that before that I installed google chrome and also worked very slow for me.
I am enabling GSO via setting dev->features |= NETIF_F_GSO;I am observing that after I enable GSO my FTP get performance reduces.setup:ftp client running on a PC (IPv4 mode)connected across Ethernet interface.Any thought on the possible issues. Note: IPv6 is enabled. System running ftp server is in running 2.6.28 Linux.
Intel Celeron, 2000 MHz (20 x 100), 400MHz FSB, s478 Northwood core with 128 KB L2 Cache 768 MB RAM: 3 * 256 MB PC133 SDRAM (3.0-3-3-6 @ 133 MHz), DRAM:FSB running as 4:3 Intel Havre D845HV (3 PCI, 1 AGP, 3 SDR DIMM, Audio) (latest BIOS, HV84510A.86A.0050.P15.0305252001) Western Digital 60GB hard disc, WDC WD600BB-75CAA0 SONY DVD-ROM DDU1612, and some generic floppy
[code]....
all in all this was a pretty good machine to run Windows XP SP3, MS office 2000 (or 2003), and some mozilla-based browser (Firefox can work OK, but with "K-Meleon 1.5.4" it's fast as lighting). It has enough horsepower to run CounterStrike at 1024*768 and play MiHD movies with just a few ocasional glitches. Plays DVDs or XVID and MP3s without any problems, and they don't seem to use much resources in Task Manager. Sound, graphics and network subsystem work very good, but this will always be a PC133 SDRAM system hence memory bandwidth problems, and not much can be done about that. Machine was used as office + internet box, with some Winamp music playing in the background and as such it was great.
Now I turned it into (dual boot) CentOS 5.4 development server for developing a nonprofit PHP site.Joomla-based contents load slower from this machine on the intranet then on the regular server online. It's not crazy slow (like pentium 1 @ 166 mhz) but it's definitelly not good either. I think it should be able to run much much better, especially when I remember the Athlon T-bird at 1 GhZ with 512 MB PC100 RAM used to be much more responsive while running web apps on Mandrake 9 (when it came out) with KDE WM, while this cellery runs just server in init 3 (no Xorg or Gnome, just command prompt).
Please advise me how could I enhance the speed of the system. CentOS 5.4 was installed with all settings on default. Everything worked plug'n'play, didn't need to install anything extra. Machine primarily runs Apache2 with PHP and MySQL, SSH and SFTP daemons, not much else I guess. No GUI, mostly it runs headless anyway. I'm mostly annoyed by the way it serves pages, it's like it takes up to 6 seconds to precache some complex PHP page and then poof! whole page appears at once. I'd much rather if it served the contents of the page part by part, gradually filling in the details. I'm not sure if (and how) that can be achieved though. I'd like to optimize servers (mostly Apache) and maybe net config to run smoother and faster.
