Re: [rt-users] Reduce RAM usage of mysql and apache on RT install 1GB Ram vps

2011-08-27 Thread Ruslan Zakirov
Loading less translations of the interface saves memory. Module that parses
po files is not memory efficient and I can't find cycles to improve it.

Using RT on Apache with mod_perl without reverse proxy in front is also
memory hungry setup. Use reverse proxy for mod_perl setups.

Simple fastcgi is a little bit better as web server acts like proxy and one
fastcgi process may serve several server processes. However, each fastcgi
process started on its own by web server and don't share memory.

Recent RT versions have external fastcgi server that uses forks and shares
memory.

I think external forking fastcgi server with nginx/lighttpd/Apache in front
may give most memory effective setup.

 Which RT Version do you run?

 It would be great if you could share your experiences with me.

 We moved your RT 3.8.6 some weeks ago from a 32bit Debian lenny machine
 to a 64bit Debian squeeze VM with 4GB RAM.
 Since then the apache processes eating up all the memory.
 As we don't changed the RT Version I think it's not RT fault.
 I guess there is a memory leak in one of the Perl modules.

 We use all the Perl modules from the Debian repository.

[rt-users] Reduce RAM usage of mysql and apache on RT install 1GB Ram vps

We have about 20 users and I have access to a virtual server with 1GB ram.

You could tune mysql down, and tune apache to only have 2 or 3
children, but the admin time spent doing that is worth way more than
1G of RAM these days.  If you do tune it down, you'll be trading
database performance and making RT really slow.
