This is my first question here and i may not be very well versed with AIX too. But neverthless i am trying to solve the problem at hand and this is what i am stuck with.
We have an AIX 6.1 machine up and running. But the CPU usage as shown on topas seems to be always 100%. (user ~70% + kernel ~30%).
Hi.
Since a few days ago cpu usage is high just because of a system process located at /usr/sbin/atd. The load averages are most of the time at 15 - 21. top command is showing the high usage too. about 60% - 70% for system (sy).
Why atd is processor hungry?
I have already tried /scripts/fixeverything --force and upcp --force.
Hi!
Is it possible that server log files can cause high cpu usage?
My Load Averages are very high (over 12). It appears that mysql is causing it.
There was a slow-query log that was 450MB heavy.
I disabled it. It seems that the loads went down a bit.
Are there any other logs I should consider emptying or disableing?
Two dedicated separate servers running with identical configuration of hardware (Dual E5-2620 32GB) in similar environment (CentOS 6.3, Apache+PHP+MySQL) serving similar tasks, but behaving in different way of processing Apache web server - CPU usage 17x times bigger in server which has lower requests.
CPU Usage: u2.03 s1.05 cu316.97 cs0 - 4.35% CPU load
11.9 requests/sec - 5.3 kB/second - 4
Hello All,
I upgraded to 12.10 from 12.04 like two days ago and it's been running flawlessly, actually. What's even better though was that my system theme was 12.10 compatible or Gnome 3.6 compatible, rather I should say.
Nevertheless, I use Psensor pretty much all the time and even the Gnome System Monitor backs this up but my CPU is constantly running at like 40 - 50% usage all the time.
I'm bit confused about how to get the number of context switches using a new system call in Linux, so the definition that I need to use is sched.h, but this implementation is quite hard for me...
Please, could you say me any ideas? Create a new function/system call in order to get these counters updated (voluntary and involuntary context switches).
Thanks a lot in advance.
I have a Social Networking site that runs on a single LAMP Server that handles everything.
The average RAM usage per Apache process is 43 MB.
Is that amount roughly within the expected range for a Social Networking site, or is it too high?
If it's too high, where and how can I look to bring that average number down?
(If you need more details to determine whether it's within the expected range
I have a home server sometimes running at a high CPU usage rate of about 50 to 70 percents.
In htop, my favorite process manager, I can sort the processes by CPU usage, but often there isn't any process consuming more than 0 % CPU.
I have 1GB Linode VPS with a standard LAMP stack. Apache is tuned fine but for some reason MySQL's disk usage is high. This is causing really slow site load times. RAM and CPU usage are fine.
Can anyone give me any pointers on tuning mysql's disk performance? I'm using InnoDB.
