I'm trying to figure out how to tune my litespeed setup for my 512Mb slice at slicehost.com. The server will be running two rails apps and mysql, both apps are low volume for now. 1. On a 512Mb server what are reasonable limits for Memory Soft Limit and Memory Hard Limit for a Rails app that on average takes 60Mb (of non virtual memory) per process? 2. Memory I/O Buffer - This is set to 120M by default, can I set this lower (say 10M) so that it doesn't end up chewing up a lot of memory?
