General :: Web Suddenly Slower, Attachments Won't Attach?
May 10, 2010
Recently installed debian lenny.Running very well.WM: ratpoison.Suddenly, today, the internet runs much slower.ONLY ON THIS MACHINE - the parallel windows machine, off of which I was successfully weaning myself, is not having this problem, so it's neither the router nor the actual internet connection.Specifically: I can't attach a document in yahoo mail.I tried it in iceweasel, same problem, so it's not the browser.I piped the output of "top" for a minute or so to a text file, which I'm attaching.

OpenSuse 11.2
LXDE (Latest version)
It used to have a lightening speed. But now every application is taking few seconds to start, even on Konsole, the commands take some seconds to get typed ! (I literally have to wait for cursor to move and commands to get typed on Konsole). Folders are taking some seconds to get opened !
I rebooted the computer but that proved to be useless.
Here the ps output:
Code:
anisha@linux-uitj:~> pstree -Apuh `id -anisha`
id: invalid option -- 'i'
Try `id --help' for more information.
init(1)-+-acpid(1054)

Im experiencing a strange problem with 10.04. When it first boots up its reasonably quick (as snappy as Gnome ever has been) but after its been running for a day or two it gets ununsably slow and has to be rebooted.
I dont see how it can be anything to do with my hardware as it runs OK when first started. Ive monitored RAM usage and it doesnt seem to differ much. There's always the same amount unused.

Running Postfix 2.6.1 on Slackware 13.0.I noticed that if I send an email with a large attachment(namely more than 500 KB) from another computer using this postfix server as an smtp server, it takes up to an hour to send it.It's almost like postfix is configured to send large emails later with a lower priority.The client computer and postfix server are within a GIGABIT LAN so upload 500 KB isn't an issue.

If I start a process with nohup:
nohup WHATEVER &
then how can I see it again? I mean how to attach my terminal to it again under Linux, e.g.: Ubuntu 11.04 - just like with the screen package.

I have a question about NFS and CentOS 6.0. Here is the environment: Server running VMware's esxi 3.5 (Fully patched) 10.1.1.50 Server running CentOS 5.5 with NFS. 10.1.1.51 With the systems in the above config everything is working fine. Install a new hard drive in the CentOS server and install CentOS 6.0. Use the same IP 10.1.1.51. Configure NFS, the VM server can't attach to the NFS share.
Here is the config of the NFS server:
Firewall Disabled
SELinux Disabled
NFS installed and running.
NFS-Utils installed.
Contents of /etc/exports
[Code]...
I have confirmed I can telnet to the ports listed. Any clue why the setup with CentOS 6.0 doesn't work? Is this a NFS4 vs. NFS3 thing? Is there a way to force CentOS to use NFS3? I am pretty sure the CentOS 5.5 server is using NFS4.

I'm using Thunderbird 3.x on Ubuntu (Linux). When I save an attachment to my computer, the file gets saved with only the owner (me) having read/write permissions. In other words, the file gets saved as -rw
Frequently, I want my group to have permission, or to give read permission to everyone. Is there a way to do change Thunderbird's default file permissions so I don't have to do this manually every time?

I'm am not remotely familiar with the linux operating sytem and just need a simple 'cut and paste solution' that will allow me to send .gz files as mail attachments, from the command line.Recently I moved my website to new hosting company, they are using cpanel and I have set up a couple of commands; the cpanel scheduler runs them for me as required.
1.creates an mysql dump and saves it to folder ( in root of my space )Works fine.2. delete the file created above, after 15 mins. Also works fineWhat I really want to do is email the .gz to myself before it is deleted, this is were I am stuck.This is possible ( I believe ) but it is beyond my understanding and ability to write the scipt/command that will make this happen.Please make any instructions really simple and clear as I am really new to this.on the server and this information is provided below and may be helpful to you (but I certainly to not know anything about this type of stuff)

I am trying to set-up a script that will go to the folder and attach all files from that folder to the email without having to specify name for each attached file.
Below script requires exact name of the file and then puts file context into the emails body.
cd /home/denis/Test/
mail -s "log files attached" smith_denis@ymail.com <log.txt

I have bought one of the new Logitech wireless mice for my laptop, but it seems too "fast" - a small movement results in massive movement on the screen, its much faster than the old corded mouse I am using with my desktop.

While converting some images using ImageMagick, I noticed a somewhat strange effect. Using xargs was significantly slower than a standard for loop. Since xargs limited to a single process should act like a for loop, I tested that, and found it to be about the same.
Thus, we have this demonstration.
Quad core (AMD Athalon X4, 2.6GHz)
Working entirely on a tempfs (16g ram total; no swap)
No other major loads

I am running openSuse 11.2 (32-bit), my CPU only supports 32-bits. I have a hardware RAID device. My system has 4GB of RAM. When I configure my system to only use 3GB, 2GB, or even 1GB, using mem=1024M in grub, my RAID performance is much better then when letting my system use the default 4GB available.Can anyone explain to me why this is? Is there anything I can do, i.e. kernel configuration, that will help performance when running with all 4GB enabled?

I have a big archive with about 10000 documents in a usb stick. What I have noticed is that browsing of that archive with gnome is much slower with ubuntu than winXP ( dual boot , same PC ) where it is almost instant.I have disabled assistive technologies and installed Thunar file browser. It improved things but again the lag is important. Linux is in general much faster than windows, so I wonder why is it happening ?

I've found myself using the -v flag for lots of applications less and less (especially for trivial stuff like tar and cp). However, when I did and I was, say, unzipping a large file, it would take longer than when I didn't use the -v flag.I assume this is because the terminal has to process the text and I'm filling up whatever buffer it might have. But my question is, does this make the application actually run slower or does it complete in the same amount of time and what I'm seeing is the terminal trying to catch up?

Debian lenny, old install (I've upgraded to lenny when it was just about to become the stable release), versus windows 7, fresh install.Comparing browsers speeds with numion.com/Stopwatch.html, I had results such as:Iceweasel (firefox) on linux: from 9.154 seconds to 21:860 seconds (the same webpage, reloaded)Firefox on windows: 4.32 seconds - and never much slower than thatThe fastest browser on linux was Opera, ranging from 8.562 to 5.503 secs to load the same page, but even internet explorer beat/match it with its timing of about five seconds.
I have not other browsers on windows; on linux there is aroraonqueror (KDE3), kazehakase, chrome, and dillo, besides text browsers. I didn't test on dillo; Kazehakase and chrome were the only ones which had nearly decent results, but still very bad, 11 to 13 seconds for chrome, and 21 for kazehakase. Konqueror just seemed to never finish to load the page, I gave up when it was still loading somethingfter nutes and 5 seconds.'ve emptied the cache every time I would test, and I was running almost only the browsers and not much else. Whatever comes by default on windows, and on linux, I was on openbox, with nothing much going on I guess, I think the most memory consuming processthe time, besides xorg and the browsers themselves, was dictd.
I've researched a little bit about, but not enough to make a list of possible things to change in order to improve the speed on linux. Most of the time there are people just agreeing that on windows the rendering is faster, and other people saying that with them is the opposite, with some minor variations like people saying that linux is faster for plain downloads while windows is faster for web browsing due to better graphics.
(by the way; I haven't installed any graphic card driver on windows, which is still running on 1024x768, while linux runs on 1280x1024, with the "nv" generic driver, without fancy options, not supported by my old card) The closest to a suggestion of possible solutions was someone saying tha compilation may affect performance, I guess it was both about kernel compilation, and the web browsers themselves.I'll google a bit more about how to "compile for speed", both kernels and programs (maybe the x server

I am new to linux but will try and be as precise as I can. I have a Dell Insp. 1545 with 3GB ram with 10.04_64
Problem: Rather out of the blue upon login, from the time of entering password to the desktop, is MUCH slower. I have no splash enabled and there is some reference to AppArmour profiles (it sits there at this apparmour reference , then sits trying to load desktop). However, I have never configured apparmor. Finally, on last login, there was some sort of screen corruption prior to getting to desktop.
Prior to all this i noticed that firefox "blinked" when I was using it, and then said that it needed to shutdown/restart for updates. I did notice at that time two of my previous tabs sortof acted oddly (moved around then disappeared).
I have no SSH/Server software etc activated.
I did change visudo so that sudo timeout shorter than it was. However that is the only modification to the system recently.

using mint 10, now after updates my system is barely working. The programs were no longer showing in the task bar, and the system was running much slower.
[code]...
This repeated over and over again. My temperature was never to high 40-55, and I found a suggestion to update my kernel to 2.6.37-020637. After doing so there is no longer the thermal limit exceeded error but the computer is still running poorly. The system is slow and again no programs are showing up in the task bar when open.

at my work we have upgraded suse to 11.2, thus we also got an upgrade of thunderbird 2 to 3.
When I now save attachments to our network disks it writes them as user=rw (600), and no longer as 644. I do not want to do chmod for every attachment.When creating a file by csh or bash terminal or downloading a file by firefox it does write the file as 644, which is good.
Can someone please give me a suggestion of how I can solve this problem? Is there something I have to change in the prefs.js file?

I have set up a Sympa list serv server and everything is working fine for the most part. One issue that I am running into is sending files over ~580 KB in size (just a normal .txt file) are not going through. I am getting the following error. Impossible to distribute your message for list 'list-name' because of an internal server error.I have verified that my "Maximum message size (max_size)" setting in Sympa is get to 5 MB so that shouldn't be the problem. If I try sending the same .txt file after taking out a few lines, and the file size is ~530 KB, then it works just fine. Nothing is really jumping out at me in the logs either.

I have Internet access with Verizon Wireless and have a limit of 5 gigs per month but Mozilla Thunderbird 3.1.8 is wasting my data whenever I send large attachments. For example, when I send an attachment to somebody, Thunderbird will upload it okay but when it is finished uploading it, the message in the window then says "copying to the Sent folder" but it does not simply "copy" it, instead, it uploads the attachment all over again to the Sent folder. So the attachment was uploaded twice, once to the recipient and once to my sent folder.I am running Linux Mint 9 Isadora.Is there a way to stop this behavior?

I'm at a complete loss on this one.MY version of Firefox 3.6.10 (Ubuntu 10.04 LTS) opens all email attachments with no problem. However, my sister's machine--same 3.6.10 and 10.04 LTS--does not. Instead, she gets the following message: "(PDF or JPEG) could not be opened because the associated helper application does not exist. Change the association in your preferences."I've checked all her preference settings against mine, and they match...but mine works and hers does not. (Also verified that "Document Viewer" and "Image Viewer" are installed properly...)
