I'm running in a Ubuntu VPS and was able to easily get mod_rails up and running, but the only problem was that it was using to much memory. Apache + mod_rails was easily eating away my 512m of ram on the VPS.
I tried chaging the RailsPoolSize configuration but that didn't seem to do anything.
For now I have switched back to mongrel with 2 clusters, and that with apache is easily under 256m of ram, which is far better for this setup.
Any advice or info on configuring this? I would like to use mod_rails as it is easier to deal with, but if it sucks all my resources away it will have to wait.
Thanks for any information!
