Hello:
I want to know how to know which startup services are needed. I feel my lappy is becoming laggy, and it's not the disk space.
And I don't know if it had to do with the latest update or something else I don't realize.
I'm using latest antiX [antiX-M11-686 Jayaben Desai]
System is: P4 2.4 GHz IBM, 1.2 GiB of ram, 9 GiB system, rest is /home and such.
Regards.
Tan.

Check upgrade went ok by typing # apt-get -f install If there are issues, see this thread: upgrading-antix-m11-t3473.htmlIf myspell-el-gr is still an issue, delete the /var/lib/dpkg/info/myspell-el-gr.postrm file then do apt-get -f install

Once in a while, that always happens, so then I remove them, as suggested. Nothing about "myspell-el-gr". And, ontopic, how can I tell which antiX process or service is needed or not ?? Maybe there is a process unbeknown to me lying under the screen (or under my nose), that is using CPU (apart from listening audio music). Also, what means "Regenerating hal fdi cache ... " ?? Thank you again.

htop may help with what is causing lagginess.
In Documents folder, there is a file called startup that may help in which services to remove.

A long list, and I barely understand both this list and startup.txt on Documents folder. Htop "tops" at 33%, because of chrome in suppose. But after opening / closing sysv-rc-conf, it tops at 100%, and I feel the slowdown. Another thing: Roxterm always makes me wait 5 seconds before I can type commands. So is this caused by a program that I executed unbewillingly ?? Code: tan2@tan2:~$ pstree

Please post the output of the top command. Run: Code: $ top -n 1 > top.out Then copy and post the contents of the file into a post here. Please put the output between "code" and "/code" tags where the quotation marks are replaced with [ and ]. This will make it easier for us to read. Also, as other have suggested, run the htop command. Choose to SortBy CPU% if that is not already set. This should give you a good idea of which process or processes are hogging the cpu.

The only program that tops 100% now, is the sysv-rc-conf. Only seconded by chrome. The strange slowdown was compared with the antiX system I had before: fast, light, and just now it has become to behave like the Windows OS: the more I use it, the more slow it becomes (now referring to AntiX). I don't understand this. And I have alwas used chrome since the start, this is the only process that tops cpu use (chrome tops at 20% max), with it and all system, near 33%. Maybe an update with a bug, don't know which. Thank you. I hope I did't bother you.

I gave you the wrong instructions for capturing the top output. One way to get the output is to just run top then use "q" to quit and then copy-and-paste from the terminal window. Or cat the file that you capture and copy-and-paste from the screen. Your load average looks high for a single core machine: http://blog.scoutapp.com/articles/2009/ ... d-averagesIt looks like you might have two copies of sysv-rc-conf running. You want to close those and then try looking at top and htop again. If you can't simply close them then, as root, try: Code: # killall sysv-rc-conf If they survive that then nuke them with: Code: # killall -9 sysv-rc-conf You want your load average to be well below the number of cpu cores when not much is happening on your system. I'm doing a bunch of compiling now on a dual core system. Both cores are pegged at 100% and the load average is a little over 3. The machine is still very responsive. If I can read between the ansi correctly it looks you used: Code: 1.1G out of 1.2G RAM
21 Meg out of 1 Gig Swap that memory usage looks high for antiX. Maybe one of your apps is using a lot. Having to swap will really slow things down and could cause the symptoms you are experiencing. Others may know more about this than I do but I would try shutting down museek(d) and/or the gvfs stuff. You could even try turning off the Rox pinboard which will disable desktop icons. One approach would be to shutdown X-windows (exit --> logout, the ctrl-alt-f2, login as root and run /etc/init.d/slim stop). Then run top and htop from the virtual console. This would tell you if the problem is related to something in X-windows or not. This would cut the places to search for the problem in half. You should be able to start X-windows again by running /etc/init.d/slim start.

I quit using Opera Bitjam because it would lock up the desktop and spike out CPU to 100% depending on what web pages I visited. I forget what process opera ran that I had to killall -9 even after I closed opera. @tanian, here is my screenshot while running Iceape while responding to this thread on a P3 IBM a22m. maybe if you post yours when it is running chromium we can see what is sucking you down.

From now on, the link is on my favorites. Great learning from that. Quote: It looks like you might have two copies of sysv-rc-conf running. (...) I guess I myself explained wrong the situation. The issue of this topic, the reason I OPed, was NOT related to sysv-rc-conf ion the first place. While I do the homework (any WORK that you do at home instead of your real workplace) I let that process occupy more and more memory, and now the lag is greater than before my first post. SO next I did was this: Code: 12 root 20 0 0 0 0 S 0.0 0.0 0:00.03 bdi-default
tan2@tan2:~$ killall -9 sysv-rc-conf

Quote: You want your load average to be well below the number of cpu cores when not much is happening on your system. I'm doing a bunch of compiling now on a dual core system. Both cores are pegged at 100% and the load average is a little over 3. The machine is still very responsive. Thanks again; I think we owe this to the linux architecture. After I read the link, I couldn't believe that I still could use the browser for replies. (Well, with a little lag, of course) For now, system seems normal. However, I'm intrigued that this might be X-related - the chrome browser is the major CPU eater; I though changing inter-tabs / reloading tabs should'nt be any issue. Quote: that memory usage looks high for antiX. Maybe one of your apps is using a lot. Having to swap will really slow things down and could cause the symptoms you are experiencing.
Others may know more about this than I do but I would try shutting down museek(d) and/or the gvfs stuff. You could even try turning off the Rox pinboard which will disable desktop icons. The ram usage is high at moments, that is also part of my query. The museek daemon is still not closed?? Htop confirmed nothing about museekd. That, also want to kill any service, but not manually. I remember having configured the client in order to do that. Interestng. On the gvfs stuff, I am actively using my USB stick to interchange files; I hope THAT is not the cause of the slowdown. ROX pinboard: I have and use some desktop icons, besides that doesn't cause any lag. To diagnose the X-window, I will have to logout; so if double-post is permitted, I will do it and post the results in the next post. ! And pardon me for the loong reply.

(aproximately adjusted to margin, so nas to be legible) And the CPU is ok (supposing because I was out of X-window). ... Still, I want to know IF I have not-needed programs/services: I want chrome to fly on my old P4, with 20 tabs open!! rokytnji wrote: I quit using Opera Bitjam because it would lock up the desktop and spike out CPU to 100% depending on what web pages I visited. I forget what process opera ran that I had to killall -9 even after I closed opera. @tanian, here is my screenshot while running Iceape while responding to this thread on a P3 IBM a22m. maybe if you post yours when it is running chromium we can see what is sucking you down. Attachment: The attachment snapshot-2011-12-10-1.jpg is no longer available The first browser I used when installed AntiX, 6 months ago, was the default Iceape, slow, then Opera, also slow and buggy sometimes, so in this very laggy lappy I celebrate 5 months using Chrome (altough I use Firefox on the other PC). Almost the same motives as you. I don't think thats of help by now, as I have just restarted the X system, following suggestions, and as you can see my cats of this post. But as you helped, I attach the capture on Htop. For now, I'm just running chrome and Roxterm and audacius and thunar. Are there any process/service not needed ?? How do I know that, without affecting the system ??

This looks good now. Whatever was causing your problem got killed when you exited X-windows. This means you really don't have to concern yourself with cutting back on services. Looking back at your pstree I didn't see any unneeded services but I did see chrome running directly under init which seemed a little strange because it was also running under Rox. It could be benign. Maybe where it ends up depends on how it was opened.
Instead of looking for services to kill, I suggest you keep an eye on your load average and when it gets up over 1 (or over 2) when you're not doing much with the system then try killing off processes that are running under X while running top or htop. Remember, there will be a slight time delay (about 1 minute) for the left-most load average to go down after killing a process.
My wild guess is there is a problem with nacl_helper (native client helper) in Chrome. I don't know what it does but it seems to have been causing other problems. If that's the culprit then you may have to periodically shut down Chrome when your system gets sluggish until you can get an updated version of Chrome. Again, this is just a guess.

Well, I guess you're right. I created a link to open chrome under Rox. And, sometimes Chrome becomes slow after opening more than 10 tabs; just sometimes (very few indeed), than I had to call Htop to kill it manually. Maybe some "zombie" processes just don't want to die after being killed  But I cannot tell for sure, as I'm not a linux expert. So, if you're telling me that there aren't any unneeded services, then I may rest relieved of knowing my system is in good state. If I have the time, I'll consider opening chrome from console script /bash instead of from Rox, to prevent extending a possible issue with it. The processes that are running under X, are those with runlevel 5, am I right ?? Regards from my part, and thank you for your time. Tan.

Just to see if chrome is the culprit, run iceape browser for a while instaed with lots od tabs open and see if the same happens.
It might also be a flash issue if one of the tabs goes to a flash movie site.

sometimes if you use a cli app in the terminal and close the terminal from the x button, it stays open in the background peaking at 100% cpu usage, you either need to kill it for good or reboot your system. also sometimes when the browser freezes and you kill it, it remains open in the background peaking at 100% CPU, i get this about once a week with with firefox/iceweasel and you have to kill it from htop. screenshot
