Hi all,

Recently I started 2 local galaxy servers on an internal Linux PC. I noticed that the main WSGI process uses a lot of CPU time – see the output of ps command below:

$ ps aux | head -1 & ps aux | grep wsgi

[1] 5293

USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND

galaxy    26685 59.6  0.3 457332 125224 ?       Sl   Sep14 34447:36 python ./scripts/paster.py serve universe_wsgi.ini --daemon

galaxy    19346 38.9  1.9 1098388 634772 ?      Sl   Oct17 4451:59 python ./scripts/paster.py serve universe_wsgi.ini --daemon

From this output, the first galaxy process used 59% of the CPU time in the recent month, it is 34447 minutes!

The second process used 39% in the recent days.

Also the top command returns similar results: both galaxy server use more than 90% of CPU time, even if nobody is accessing galaxy.

Is this normal?

Do you have the same %CPU in ps command?

Can this be configured/minimized somehow?

Why is the CPU usage so high, if nothing happens? Is this a feature of WSGI?

Sebastian
