What is effective_cache set to ?
Increasing this seems to have helped significantly a web app. Load times
seem magnitudes faster.
Increased it to effective_cache_size = 12288 # 96MB
What is a reasonable number?
I estimate I have at least 1 to 2 GB free of memory.
Don't want to get too carried away right now with too many changes.. because
right now we have very few connections to that database (usually less than
10), but I expect it to go to a norm of 20+.. so need to make sure I won't
make changes that will be a problem in that scenario.
So far only see one setting that can be an issue: work_mem
so have it set to only 32768.
