Sounds like a reasonable starting point. You could certainly fiddle
around a bit - especially with shared_buffers - to see if some other
setting works better, but that should be in the ballpark.
I tend to set it a bit higher on EC2 to discourage the VM from
overcommitting memory I need. So,
I'm running pgsql on an m1.large EC2 instance with 7.5gb available memory.
The free command shows 7gb of free+cached. My understand from the docs is that
I should dedicate 1.75gb to shared_buffers (25%) and set effective_cache_size
to 7gb.
Is this correct? I'm running 64-bit Ubuntu 10.10,
