Complaints about Ruby memory use: false?
I just checked two long-running deployments of mine (one Rails and one Merb) and the Rails application processes totaled about 80 MB VSIZE and the Merb combined processes were about 70MB VSIZE. In my setup, add in about 7.5 MB for nginx and 10 MB for memcached. Nginx and memcached are shared by all web apps, long-running and experiments, running on this particular server.
Have you seen excessive memory use in your deployments? If so, what are your setups? On the other hand, I would also like to hear about low-memory deployment schemes. I have not tried Phusion Passenger but I heard good things at MerbCamp 2008 about reduced memory use with Passenger.
