[DRE-maint] Bug#585976: High memory usage

[Laurent Bigonville]

Package: redmine
Version: 0.9.4-3
Severity: normal

Hi,

I'm experiencing high memory usage, several process like this one:

www-data 13105  0.7 11.6 256036 242536 ?       Sl   09:20   0:25 ruby /usr/share/redmine/public/dispatch.fcgi

After reading[1] and [2], I reduced the GC interval in dispatch.fcgi
from 20 to 15 to 10 and then to an empty value and everything goes
better. With 15 it seems that it never goes higher than 148m (7.3%) per
process, and with an empty value (aka lets rails decide) the memory
usage is only 70m (3.5%).

I didn't see any major slowdown (well I feel redmine a little bit
slower but it's difficult to judge) on my installation (with max 3 users
doing things at the same time).

What do you think should be the right value? For what I've read it
seems better to leave rails decide alone.

Cheers

Laurent Bigonville
