Redmine

That's what my passenger processes weigh in at (from passenger-memory-stats):

5130   269.5 MB  101.3 MB  Rails: /some/path
5186   271.3 MB  99.2 MB   Rails: /some/path

That might be little more on the lower end of the spectrum, because I externalized the caches to a memcached server (so the cache is not in-process), and while your figure seems a little on the higher end of the spectrum, it's nothing uncommon.

Thanks Felix! That is good to know. I will see if I can find out more about the memcache solution.

I wouldn't bother with memcache if you don't have at least 2-3 redmine processes running at all times, if you only have 1 or 2, it does only take the memory load to another process and will only mean more work for you.
