Debian Installation :: Dismal Wireless Performance ?
Aug 16, 2010
Just installed Sqeeze and works almost flawlessly on my Clevo w870cu. My machine has a realtek wifi card so I installed the vendor specific driver (see below). Wired performance is super, wireless performance however is very bad on Linux. On "Windows 7" (dual-boot, which I never use, only in these cases to sort out problems...) wifi performance is slightly better. My smartphone's visual wifi-analyzer (I couldn't find a Linux equivalent...) showed good signal strength (aournd -50db a 4 m distance from router) an little-to-no interference from neighboring channels.
Here some hardware information:
1) Modem: Motorola SBV 5120 E
2) Router: Sitecom WL-350 (300N)
3) Wifi card: Realtek Semiconductor Co., Ltd. RTL8191SEvB Wireless LAN Controller

I am running karmic and have wireless performance which is terrible on the EEE 1000HA I see it as low as 1mbit at times and others at 24mbit and briefly at 48 and 54mbits. running an Internet speed test with wireless I get pathetic speeds as low as 15Kbps, Its 5 feet from the wireless router ... and other machines that are wireless in the same area show 54mbits and perform great ... any one solve this problem with the asus EEE1000HA running on karmic?

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?

My wireless was connecting fine, but it was impossible to browse with. So, after searching around for a while I found a thread where it said to enter this and reboot.
#echo "net.ipv4.tcp_moderate_rcvbuf=0" >> /etc/sysctl.conf
#echo "net.ipv4.tcp_default_win_scale=0" >> /etc/sysctl.conf
But after entering that and re booting, now I cant even connect to the wireless. It says connecting but times out.

I have ubuntu lucid running on Dell 230 PC, linksys WPN600 N wireless PCI network card connecting to a Cisco E3000 dual channel router.
Kernel: 2.6.32-33-generic
Installed Ralink driver v2.4.0.0
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 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.

Is there any program for GNU to calculate CPU's performace in marks (should support multi-core CPUs)? So it will be possible to compare performance of different CPUs.

Is there any way of improving performance with the GTX 470 using Wine software with Debian Squeeze?
Installed version of Wine is 1.3.6 tested with different versions of nVidia drivers including the latest one, still VERY slow performance and many quality settings are in red. Setting WoW to use OpenGL improved the performance, but deactivated many quality settings in red, unfortunately. Looks to me as it's using lower features than OpenGL 2.0?? So what's up with that? GTX 470 supports OpenGL 4.1 so I suspect it's an limitation in Wine software, can anyone confirm this?
Default kernel 2.6.32 is used in all of this. The computer is an Intel Quad at 2.4ghz + 4 GB DDR 2 or DDR 3 memory.

How to start. I know the problem is polkitd. But how can I analyse the source of the problem more deeply? Something is calling polkitd permanently, but how can I find out which process it is? My system resources are limited.

My machine is a laptop Dell Inspiron 1545.The command lspci correctly list this device but i can't change the resolution and preferences. Also my monitor doesnt show a high quality image.Another question, how can I probe my video performance in Debian?

I just have a few questions about LVM and RAIDs. It seems they are basically the same thing. Is this correct? I can add two drives together on both of them and it appears as a larger drive, along with other setups like raid1 and raid5, etc.. And is there a difference in performance between them?
And my second question.. I know one is stripped and one is not, but is the performance between a raid1 and a raid0 the same? I've been told that raid1 is faster than raid0 because the data is written twice.. and therefore can be read from two different disks which equals faster read speed, but slower write speed since it writes to the two.

II installed flashplayer by every different method I can so far, and all of them have the same problem. This problem presents itself, for example, while playing a video on ...... As the video loads, flashplayer is fine, but as soon as it starts playing, the browser tab begins to run at roughly 1 frame per 10 seconds. When I turn the browser priority to maximum in System Monitor, it improves slightly, going to about 1 frame per second. The strange part is, my CPU and memory usage barely spike at all, to less than 30%. This happens regardless of browser (have tried iceweisel and chrome). It happens with hardware acceleration on, and off. I have tried installing flashplayer from the tar.gz on the adobe website, from the repository (all three packages), and manually placing the plugin in the browser myself. The issue presents itself the same every time.
My system specs are: 1.83GHz duel core intel centrino processor, 3GB RAM, ATI Mobility Radeon HD 2600. Nothing fancy, but flash player performs as flawlessly as flashplayer can under windows (and also performed well in my previous Ubuntu 10.04LL install).

I have 2 ASUS Boxes (one with 8GB, one with 4GB) When both mtus are set at 7200, using scp to copy a 56MB file takes 2:06. If I reduce either mtu to 1500, the speed is 2 seconds. I'm wondering if this is some kind of kernel bug or driver bug or what. For the moment, I've lowered the mtu to 1500 to get the performance out of the machines, but find it interesting that what should make it faster is actually slowing down. Where should I post this to get it looked at? Is anyone else seeing it.I see a similar performance issue with smbclient too.

Ok first off, I love debian, but on my new notebook I am getting a little frustrated with the terrible, video performance.Direct rendering is enabled on both systems, and openGL is working (I can if I wanted to use compiz etc...) fine on both systems, just running slow on debian.
I have tried Lenny, Squeeze and Sid, I have compiled the intel driver (and Mesa3D) from git and got it working (I am sure its working because its given me a slight boost), I ahve also tried building the latest stable (and RC2) kernel.If I install ubuntu 9.10 I get pretty decent 3D performance, its not ground breaking, but hey its an intel chipset so I am not expecting to kick the latest nvidia / ati card's backside.I really dont want to use ubuntu, I find it unstable when compaired to debian, but I also want to be able to play the odd game when I am bored, and at the moment I just cant do that under debian

I have an ATI Radeon x1300 graphic card on an Intel platform.Since the last reinstall my Debian Squeeze system shows very poor performance in glxgears,only 80-90 FPS. Last time I had a problem the kms setting in the kernel. I disabled the modding setting in GRUB and then glxgears showed about 900-1300 FPS. Now,the problem is back, even though I made the same setting in the boot loader.

My last laptop was replaced (I gave it to my step-dad, his laptop broke and I bought myself a new one).
I am running Squeeze (as I was on my other laptop) and everything is fine except for the games. On my other laptop games like OpenArena and Warzone 2100 ran perfectly fine, but on this laptop, they are impossible to play. The game will open, but everything is so slow and choppy that it takes a couple of minutes to even move the cursor to the exit game buttons.
My current laptop is an HP ProBook4525s with the current specs:
AMD Athlon Dual-Core P340 2.2 GHz processor
2GB DDR3 RAM
ATI Mobility Radeon HD 4250 Graphics Card
I'm not sure what other information to put here, I've tried searching how to fix this and most people say to lower the resolution and details for the games but that doesn't work, heck, even Tux Kart is too slow to play!
When I installed squeeze I was informed that I didn't have the rtl8168d-2.fw firmware for my laptop, I'm not sure if that helps here at all (can't seem to find what it is for, the only things that google gives me are very technical with fixes that involve re-compiling the kernel).

I've got 4 identical 1 TB drives and would like to use them in a software RAID configuration on my home server. I'm running Debian Linux using 'mdadm' utility to manage the software RAID. I don't know how much I've read is fact or dated or even false so I decided I would ask here to get help from people who know more about this than I do. This is essentially just a file server machine to store all my data so being that I've got four identical SATA hard drives, I was thinking about doing RAID level 5. I guess I'll start here and ask if that is the recommended level of RAID. I think RAID level 5 will be fine for my general server usage. My second issue is partitioning the four individual drives to get maximum performance / space from them. Basically just asking here how would you or you recommend I partition the drives? I was thinking about doing three seperate partitions per drive:
/dev/sda1 = 4 GB (swap)/dev/sda2 = 1 GB (/boot)/dev/sda3 = 995 GB (/Now from that partition schema above, obviously all the types will be 'fd' for RAID and the partition for /boot is going to be bootable. My confusion is that I read Grub doesn't support booting from RAID 5 since Grub can't handle disk assembly. If /dev/sdx2 (sda2, sdb2, sdc2, sdd2) are partitioned for /boot (bootable), how would you guys configure this RAID to match up equally? I don't think I do a RAID level 1 on 4 identical partitions, right?

i had recently loaded squeeze and had an issue with the 2d performance.i.e when being prompted for the root password, the shading slowly draws down the screen several times before stopping at the final darker shade. i then added the linux-firmware-nonfree package. all worked extremely well, even compiz, but i don't really care about compiz. i just loaded it to see how it performed. i then distro-hopped a bit and when i came back to squeeze the first thing i did was add the package, but the video is acting like i haven't added the package. i've searched for an answer, but have not found anything recent to indicate if xorg was upgraded or what.stable lenny works fine, but i'd rather have the nice console fonts when not in x and more up to date apps like gimp and xsane in squeeze.

I'm doing a fresh install on my netbook and have purchased an 8GB SD card to expand storage space. I'm curious as to which directories can be mounted on the SD card without affecting performance as the write times and such are much lower on the card. I know that /home and /tmp can be mounted there.

I am having a lot of performance problems since my upgrade my ATI board does not get properly supported (tried a lot but nothing really helps)my keyboard typing is horrable : i have to see at each click of it got accepted ; cannot type text properly screen performance is bad - often the screen greys out and back to color (probably because of driver)

This is my 2nd attempt at installing Debian since 5.0 several months back but I am determined to get it running this time.Install of 64bit Squeeze went well, installed the ati proprietary drivers directly from ati which resulted in horrrible performance.Uninstalled that and followed to the T. At the "aticonfig --initial" part I got the message "No supported devices detected" soI went ahead and entered the config manually. Now on normal boot I get a black screen and I can't seem to boot into Recovery mode as it hangs at Tray or ANSI.

I'm trying to do a partition alignment on my main SSD to improve SSD performance and then install Ubuntu on the SSD. I can do the alignment with no problem but when I install ubuntu the alignment is erased. Is there a way to install ubuntu without getting rid of the alignment?

I've just upgraded from a wonderfully working v.9.10 to v.10.04 so I can install Flash and allow video to work. Apparently I can't install Flash into this older version. The performance is now unusably slow and windows move around desktop in a very limited way and cascading menus lag. I did all updates before upgrading as suggested. (The machine is a Toshiba Tecra A4)

I have a 2016 Lenovo (ideapad) 500-15ACZ laptop, and just replaced Windows 10 with Debian 8.3. I can't get Debian 8.3 to recognize the wireless device. The device isn't defective, for it works on Windows 10. The Windows 10 driver is called "WLAN Driver (Atheros, Realtek, Broadcom) 12.0.0.116_ 7.35.295.2_2023.1". Here's the output of "lspci":

I have a dual boot on a netbook with windows and fedora13. When I am on my fedora boot and I try to watch streaming video it comes through in waves or not at all. I do not have the same problems on the alternate boot. There are other performance comparisons where the windows boot runs smoother and faster. Is there any work I can do in order to optimise my fedora boot in this capacity?

Lately I have noted a decrease on the performance of my Ubuntu Karmic Koala 64 bits installation. It takes longer times to open applications and documents and sometimes the windows fade to grey and I have to wait. Can anyone give me some hint on where to start looking for a solution?

I upgraded my old Kubuntu installation to 10.10 Maverick Meercat and I am now experiencing a really annoying problem. I boot my computer and everything seems fine for a while, but eventually my disk performance drops to horrible levels. It's not gradual. It's fine one second and then abysmal the next.
If I do "cp file1 file2" and then kill the cp process after 10s, there are only a couple of MB copied.When I run dmesg after the performance degradation, I see this:
Code:
[12879.434115] irq 22: nobody cared (try booting with the "irqpoll" option)
[12879.434121] Pid: 0, comm: swapper Tainted: P 2.6.35-22-generic #34-Ubuntu
