Fedora Servers :: System Clock Is Slow - Loses About 10 Seconds Every Minute
Mar 27, 2010
My system clock loses about 10 seconds every minute. The hwclock is fine. I've tried different kernel args (clocksource=acpi_pm, nohz=off, highres=off). None of these have any effect. I am running Fedora 11 with kernel 2.6.30-105.2.23.fc11.x86_64 on an AMD Istanbul node (Processor 2439 SE).
Anybody notice a slowdown in their boot times? I have had F11 (64 bit) running for about three days and it is taking twice as long to boot as when I first installed. I have not done much other than configure my wireless printer and change a few icons. I have Compiz cube effects running but I did that right away and it made no difference in my system speed. If anything I thought I should be booting faster after disabling a few things in the start up menu that I dont need.
I went from about a 30 second total boot to almost a minute to the login screen top - 15:13:37 up 11 min, 2 users, load average: 0.35, 0.24, 0.12 Tasks: 150 total, 1 running, 149 sleeping, 0 stopped, 0 zombie Cpu(s): 0.8%us, 1.1%sy, 0.0%ni, 98.1%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 3062244k total, 523208k used, 2539036k free, 31580k buffers Swap: 5111800k total, 0k used, 5111800k free, 206328k cached
So i just finally installed Debian Jessie OS, replacing Ubuntu. But now it is running extremely slow. It's not internet connection. The internet speed is running fine (Videos load quickly), but it's like the system freezes every 30 seconds or so. A video can be fully loaded but still stops and starts constantly. Just browsing the internet, or non-internet things do the same also. I switched back to Ubuntu to see if it was different on there, but Ubuntu is running fine.
I just installed linux mint a couple of days ago and everything went great but now the grub screen takes about 20 seconds to a minute to load. It's not a huge issue but kind of annoying since the one that ubuntu installed took a second and I was at the menu. I imagine that it has to do with the background picture but i'm not sure if that would slow it down that much.
I am using Opera 10.60 browser for the past one month. Generally it use to take about 20 seconds to startup but since yesterday its taking more than 40. I don't know about the exact duration but certainly its taking a lot of time now.
I am having a problem with my Fedora11, I am not sure wether it is software or hardware but this looks serious. My computer is running very slow and freezes up every few seconds. Every time I reboot I would get a kernel failure pop-up.
I've tried watching ESPN3 on several systems using F14 with no success. Everything runs very slow and after a few seconds, I get a frozen screen and then a white screen. I'm wondering if anyone else is having this problem or is it just me? [URL] Everything else that uses flash seems OK, even HD vids on ......
I'm running 64 bit Ubuntu, and on the start-up after I pass the GRUB it goes blank for a minute then briefly shows the splash for 5-10 secs and then jumps to the login screen. Also the screen is offset by about 10-15 pixels but from the login screen onwards it is centred. (It's also like this for if I'm in recovery mode) How do I fix this and Im wondering if it is a hardware problem?
The system runs just fine then all of a sudden it "freezes". For example an input box doesn't respond nor can I scroll down the page. But when the system comes out of the freeze 5-15 seconds later, it suddenly does all the input that was used during the freeze. The scroll and letters suddenly show up. I don't loose mouse control and I can do some other system functions but not all of them.

I'm out in a village and we get more powercuts than I like, and recovering the journal on my server is getting rather irritating. I'm looking into getting a cheap UPS, the powercuts will last usually a maximum of 30 seconds, so I only need a few minutes.
I've been looking at:Plexus V 500VA UPS Plexus V 1200VA UPS APC SUA750I Smart-UPS 750VA
I know near to nothing about these things, my question is will those work with a machine with a 700W PSU? How do you know? The 500VA doesn't really mean much to me. Ideally I'd like to get my desktop on there too, but that's more for convenience than anything.
Will any of these do the job? Any Linux compatibility issues I should plan for? Any recommendations from personal experience is greatly welcome Edit: I will be happy with a UPS that can inform Linux power is down, and get the server to cleanly shutdown straight away, I'm more interested in a clean shutdown than maintaining power to use the machines during the outage. Edit 2: Can UPS devices be piggybacked to one another to provide extra uptime? i.e. Could I run 2 of the 30's so when the first runs down, the 2nd carries on?
I want to set up a web server, and I want to set up NTP so to always keep the clock in sync. I have installed a very basic system (No GUI or X components), to keep it slim and thereby a little less prone to security problems. However, does anybody know what the Synchronize system clock before starting option in system-config-date actually does in terms of changing config files or permissions? I'd like to know so I can do it manually via the commandline.
I'm running Fedora 14. I'm running a Athlon X2 with 4gb memory and nVidia 8400. I'm using the nvidia drivers ver 260. I'm running KDE 4.6. I've disabled desktop effects (when turnt on they work a charm, performance issues are the same either way). If I open any more than a few applications at once, the system grinds to a halt. even working with Kwrite is painful and it can take several seconds just to move the cursor, browsing the file is almost impossible.
When I have even 7 windows open X goes into a frenzy and sticks around 90% cpu usage. Even with no windows open if I move my mouse between screens X cpu usage stays between 50% and 90%. The system is unbearably slow. i have a XP Pro system with the same spec, lower GPU and I have no problems having 2/3 Visual Studios open, Photoshop, a few skype windows, Eclipse and the android emulator the system remains responsive but with this Linux box I can't even do basic stuff in Kwrite without it grinding to a haltJust.
It seems every 30 seconds the internet lags, after that it is fine for 30 seconds. And this happens continuously. Also it seems when I am on Firefox if I am connected to a website, I can navigate the website with not further trouble. But if I navigate away and try to go back, it takes a while. I didn't update, or upgrade or anything. I am running 13.1 and have been since it came out. This just started with the internet 2 days ago. Also I have a dual boot with Win7 and the internet is fine on Win7.
After upgrade from 10.04 to 10.10 on my dual core, 64-bit machine, my miro software has problems downloading torrents. Torrent will start slow and then, after a minute or so, it slows down and stops saying "starting up". It appears there is a bug report, bug 668615, but I've found no fix.
I have Ubuntu Lucid Lynx since it came out, and until now it worked fine. I am updating regularly. Today too, I installed everything offered to me by updates manager (I looked through the list and didnt see anything I wouldnt want to update, but I dont remember everything that was there), and it asked for restart. Ok, so I restarted. Everything seemed fine. Then I tried to look at a picture, in normal,default viewer, an huh. It took 3 seconds for the mouse to select the pic, then another about 6 to open the viewer (and we are talking about a 40 KB pic). That was slow, but I thought maybe it was an accident. But no, everything I tried since goes slowly, at about a quarter of speed as before the update. I tried to remove unnecessary things with apt-get autoremove, I tried to stop or end all processes that seemed unnecessary, with no result. I restarted thrice. Nothing comes to mind anymore.
I wanted to know if there is variant of RollbackRX (www.rollbackrx.com.au) freeware or payable. RollbackRX used to Backup/Restore whole system changes in less than 1 minute before OS boot. And it does not consume a lot of free space.
I am running my Ubuntu 32 bit server on top of Windows 7 64 bit with VirualBox. It's a 2 core Atom. It's been working good for about half a year. But the last about 6 weeks the system time only in Ubuntu is going slow. About -8 per 24 hours! I can only guess because I have more things running in my Windows 7 and Ubuntu.
I can set it right by coping the hareware time to system time with this command:
Code: hwclock --hctosys
I want to run a crontab to have that command run every minute. But it don't seem to run.
I have squid running on F12 fully updated. Pretty much stock config except bigger cache size.
Over time it seems to start lagging and occupying more memory. Currently using ~400Mb after a couple of months. I'm sure its causing some lag / refreshes because if I turn if off and go direct to internet the same site I had to hit refresh on, loads instantly.
Going through the logs in /var/log/squid I don't see anything suspicious with the untrained eye, whats a better way of debugging it to see where/why the delays are happening? Its a single user setup (for fun really lol) so theres a lot of misses in access.log. cache.log just has a handful of bad img headers which does not line up with lagging websites.code...
Whenever I transfer a movie into my 16GB USB flash disk, my whole system becomes windows-like and unusable!
When i drag the file(s) into the USB disk folder, it starts out fine and pretty darn fast (25mb/sec) then slowly decreases until it's unbearably slow (3m/sec) and as a side effect my whole system starts deteriorating. I basically have to wait for the file to finish transferring before i can use my desktop again!
This has been happening with every version since Karmic (all 64bit)- I put up with it because I don't use the USB stick that much.. but lately it's been my go to source for transfering large files to/from work.
My system went for three days w/o a software update... Is this normal(anyone experiencing this?)...?
It seems like to me.. Fedora 13 has a longer update interval than Fedora 12.. I remember back in Fedora 12 I get security updates like every other 12 hrs.. (I know as with security patches the less the "better"(in some way))..
But I am still concerned.. security updates has been slow for me.
I am currently running Fedora 14 on an x86_64 system that acts as a whole house server for named, dhcp, nfs, nis, htpp, samba, etcMy issue has existed for a few years and I am just now getting around to posting about it.I have a simple samba configuration for sharing files to a windows VM on another box.Here is the config:
[global] workgroup = NERD server string = Samba Server on NERD
I installed Fedora 12, 64 bit on my Dell Latitude D820 laptop with Core2 Duo processor(7200 speed) and 2 gigabyte Memory.
I have updated the yum. I have enabled the rpm repositories.
It is very weird that my system suddenly works very slowly and hangs. every time I login after a while the CPU usage goes up to the end with out any reason!
Before this I had installed Fedora 12, 32 bit and I had the exact same problem.
I have installed Fedora 6, 7, 8, 9, 10 and 11 on my laptop before and I had non of these problems with them.
The interesting point is that after hanging my system works constantly slow even when I restart my system! It is slow even in booting the BIOS and start up and choosing the kernel page!
The only remedy to get rid of the slow working for a while is to Shut down the system completely and turn it on again. Restarting do not make it work normally just shutting down makes it normal for a while.
I have a FC12 machine installed with CUPS and a CUPS-PDF printer. Printer are shared and works fine with this URL:
I have both client machine Windows XP and Windows 7. Both has setup the above printer and print fine without any problem. I can get the PDF file from windows test print. The only problem is I face is wait for around 20 seconds for printer dialog prompt out when I press print button in Windows 7. However, my windows XP never t have this problem. The printer dialog prompt out immediately when I press print button.
