Hardware :: Where Bottleneck Is And Any Suggestions To Bypass That Bottleneck?
Nov 18, 2010
I am trying to copy a lot of data at once.In an effort to do that I plugged in two usb desktop disks to my machine at once and started copying from to both disks at once. The data I'm copying was from two different mounted disks. Mounted disk 1 was being copied to USB desktop external hardrive 1 and Mounted disk 2 was being copied to USB desktop external hardrive 2.It was a lot slower than doing only one copy at a time. Can anyone tell me where the bottleneck is and any suggestions to bypass that bottleneck?

When trying to run MS Communicator 2007 in XP hosted by Ubuntu 9.10 using VirtualBox 3.1.6, the Communicator process inside the virtual image maxes out (90%+) and it becomes unusable (host reports VBox at 50% CPU). If I migrate that image to a Windows host, VBox does not show the same issue (Communicator process ranges from 20-35%). Creating a similar VMware image on the Ubuntu host and running it also does not show the issue (Communicator process ranges from 20-35%). So obviously there is some kind of bottleneck occurring with VBox on Ubuntu. My questions is, how do I figure out what that bottleneck is?

Is there a suggestions box anywhere? Not for technical bugs (i.e. things that don't work properly), but for features that are currently not included or that could be improved.

I'm looking for an app similar to the Disk Usage Analyzer. I would like it to treat each HDD and partition separately instead of the way Disk Usage Analyzer treats them all as one giant HDD filesystem.

This isn't truly Slackware specific but I thought who would know better than the Slackware community. My issue is I am tired of being tech-support for my in-laws trying to keep their XP and Vista desktops functioning and would like to convert there setups to Linux. Their needs in terms of applications etc are very basic, primarily internet surfing and photos. The one application they use very frequently is a DVD backup software that runs on XP called DVD X Copy, and basically it is a one click rip and burn process for them to make backups of their DVD collection. I personally do not own and have not used such applications before so I am not familiar with some alternatives. I know of lots of programs that Rip or Burn DVD's very well but what I am looking for is a dead-simple way on Linux for them to maintain that functionality. Anything involving more than a couple steps would be challenging to them as they are very inexperienced PC users and slightly technophobic. I looked on Wine to see if the program would run under Wine but did not see it listed in the database.

What do folks suggest for the system listed in the title? It is an old gateway box with the original Phoenix BIOS. Currently I have Ubuntu on it and it was working ok till I went from 9 to 10, since then it has been acting up. I run it basically as a backroom server, (file server, home automation, media), but it doesn't get hit hard. I'm looking for something lighter than Ubuntu.

I'm unhappy with Microsoft, and Apple has slowly lost its appeal due to unsolvable problems with my iMac G5. Are there any especially good books or hints about how to start for
1. buying a system with Linux on it
2. Using either an iMac or another machine that I can install Linux on it
3. low cost ways of getting Linux systems

I have a user community of about 2000 users and a samba server running on AIX that currently hosts a read-only share for the whole company.
[Released]
path = /mypath
guest ok = Yes
But now I have been requested to make this share available as read-only for some users and completely inaccessible to everyone else. The number of users who will have access is probably a few hundred and I expect users to be added/removed on a daily basis. Some of the users have unix logins, while others do not. Because of this, I hesitate to mess with user mapping because I would have to manage this every day, unless I do something with a script.
Can someone suggest a scheme I can use to deny everyone except for certain users without having to use user mapping?Someone here in my office suggested we use hosts allow or deny, since the users who will still have access are located on the same subnet. However, there is a distinct possibility that a small number of people on a few other subnets will need access. Is there a way I can specify hosts allow but still allow specific users from other subnets?Forgive me if this question has been asked before. I'm sure it must have been, but I am having trouble doing a search of the archives that will give me advice about this particular problem.

I want to record some streaming internet radio talk shows and music performances on NPR, and I'm wondering what my options are in Ubuntu. I'm looking for something that can output high quality lossless files in several formats, hopefully including mp3 and ogg.

Being that I've never done it, I don't know what programs are out there.Does anyone have any suggestions of good editing software that is both high functioning and is fairly easy to learn and use?I'm currently running ubuntu 10.04.

Because of my background with computers, my current employer decided to throw me into a project designing some advertisements and pages in our store's catalog. This was my first time doing anything like this. They gave me QuarkXpress and I learned as I went. Since I use Linux, I would much rather use Linux to do this type of work in the future. I have downloaded Scribus and ICC profiles (color profiles). The press we went with uses CMYK (Cyan, Magenta, Yellow & Black) for primary colors. Is there anyone who has done professional printing or design that went to press in CMYK (or anything) that has suggestions for doing this type of work in Linux?

I am currently using Debian Lenny and am having problems with my pptp vpn client. I can use the following software for as long as I like without my pptp vpn connection dropping out:
(1) iceweasel
(2) icedove
(3) gtk-gnutella
If a use a bittorrent client, however, my pptp vpn connection drops out within a few minutes. I have tried these bittorrent clients: transmission, deluge, tixati. Enabling or disabling the firewall makes no difference.I have searched pptpclient.sourceforge.net and Debian User Forums but have not been able to find any suggestions on settings to change in a bittorrent client.

I have installed Suse 11.3 on /dev/sdc which is a hard drive connected to a usb port. Windows 7 lives on /dev/sdb in the box. Another drive sda is in the box also. I configured bios to boot the usb drive first. Grub is installed on /dev/sdc mbr. My scheme is to allow me to boot directly to Windows if the usb drive is not powered up, and directly to Suse if it is powered up. That all works. However, I would like to bypass the grub menu and boot right into Suse, like what happens with Windows, not having to select an entry from that pesky grub menu.
What is the best way to configure the system so that this can work? I've done a lot of searching but there are too many grub horror stories in the haystack to find this particular needle. Also, I've had my share of problems recently after losing control of the boot process somehow and not being able to boot into Suse at all. All of the postings I found on the net about recovering from that turned out to be phoney in some way and I had to reinstall to bet better. I'd like not to repeat that scenario.

I upgraded my Ubuntu to 10.4 and when I boot it stops for 24 seconds at the boot menu then loads. This is the same menu you get on boot when you press Esc. How do I get Ubuntu to boot normal?

I have a persistent installation of 10.10 on a USB thumb drive installed with the Universal USB Installer. When I boot, it always brings up the welcome screen, with the languages on the left side, the big "Try Ubuntu" button in the center, and an "Install Ubuntu" button on the right. I just want to run ubuntu from the USB stick. When I click on "Try Ubuntu" the system hangs for 2-3 minutes, requires a force-quit and then brings up the desktop.
If, at the beginning of the boot process, I interrupt it bringing up the initial menu, I can select "English" then "Run Ubuntu from this USB", and it boots very quickly directly to the desktop. Before this install I was running 9.04 and later 10.04 from the same USB stick and had no issue with it booting directly to the desktop. Ideally I'd like to not need to intervene and just have load to the desktop. Do I need to make some changes to grub?

I realise that passwords are a good thing but I'm getting fed up having to enter a password just to get my wireless network to work every time I switch on Ubuntu or when I log out and back in again.
Seeing as there is nobody in the house that I want to keep away from the computer, is there a way to automatically sign-in to my wireless network without having that annoying key-chain popping up every time?

I'm running Ubuntu 10.10 off a desktop. I was using it for quite a while up until last night when out of nowhere while surfin', and browsing, the screen just turned white, I've tried restarting by powering off manually, as I couldn't get it to any other way. After the computer restarts, it might flash black for a sec a couple of times, then back to being white again, the BIOS screen doesn't even show up. It sounds like in the background the computer might still be loading up. My monitor is a 21"LCD, if that means anything?

Yesterday I was working on Ubuntu, i shut down the computer normally, and then when i restarted it like an hour later i couldn't bypass the login screen. I insert my username & password correctly and the screen goes back for one second and then displays the login and password inputs again. I have just one username there. Before i shut it down i was trying to install Eclipse, so i messed around with some files related to Eclipse only, if that has anything to do with the problem. I also have Windows XP installed along with Ubuntu 9.10.

I am using FC11. My problem is whatever application that needs access to the internet are blocked by company's proxy server. So, configuration is like
my_machine---------> firewall ----------> outside world..google and etc
Now, If I am using firefox then I have configured it to use proxy server and required login details and etc. But, my eclipse, ssh, git and all those needs internet connection as well... Is there anything like which sets all details (proxy server, user name and passwd) system wide ? So that I dont have to pass it to each application...

I have a server that said a volume was dirty and to check it at reboot, so someone did a shutdown -rF now. Only problem is the other volumes are HUGE and it will take forever, which I cant have happen. The volume with the trouble is non-critical so I could take it offline and check it that way if i can get this to boot quickly. How can I do that if its going to auto check every volume on reboot now?

I'm using Fedora 10 as a proxy server using squid, but I recently noticed that some users use the IPS's Dns to bypass the proxy and surf the web freely. So my question is, is this a problem with Squid or perhaps I can solve the problem whit IPTables.

I have a lifttime premium account at Megaupload.com. Recently I found that megaupload has blocked all IPs in my area. I have sent emails to their tech but nothing has returned!!I have tried to use proxies to download stuff from megaupload, however, none of them works for suspected bandwidth reason, not to mention that it might be slow too.

I am VERY new to linux and have managed to install Fedora 14, xmame.SDL and Wah!Cade and finally got it all working great! My final step in my setup is (since the only use for this machine is wahcade) to be able to switch the computer on and boot straight into wahcade...and eventually hide all traces of Fedora during boot. I have managed to get the login to Autologin by adding some lines at the end of /etc/gdm/custom.conf:
Code:
TimedLoginEnable=True
TimedLogin=username
TimedLoginDelay=0
However, I still get the login box but with "Autologin" on it which I have to click ok for or wait about 15 seconds and it goes away. (I was under the impression the timedlogindelay as 0 would be instant) Then immediately after that it still asks for a keyring password.
How can I just get rid of the whole login process (like a single user thing) and just have the thing boot straight to the desktop? Also, once I achieve that, how can I make it open wahcade? And can I remove all the icons from the desktop somehow?
Everything I have come across on tinternet seems to assume I know linux inside out so answering in dummy step by step terms is more than welcome. I have a programming background but I am unfamiliar with linux programs, plugins, terminal, terms etc.

I have the restricted format software installed via one-click-install. I found that in 11.4 mplayer would fail to start playing a MP3 clip, but succeed on the second and subsequent tries, but only within a short time afterwards. A quick examination showed that this was because mplayer was firing off an instance of pulseaudio, which stayed around for a while, then exited. This was not acceptable for a clip played from a cron job so I found the way to bypass pulseaudio for mplayer was by putting this line in ~/.mplayer/config:
Code:
ao=alsa
Worked fine afterwards. I don't know if this affects the ability to output audio from other apps while the sound device is in use, but I don't have that situation, so this workaround suits me.
