Ok, I wasn't precisely enough, you are right. It's brand new server,
nothing is yet configured and we have not even os installed. The number
was the overall count we expect for a whole cluster.
But the main question is: is it possible to completely avoid disk read
if there is huge amount of RAM available?

if you're using a pooler, then why would you be using 200 concurrent
connections, unless you have a 50 or 100 CPU cores/threads ?
if you have 1000 transactions to execute on a 32 core server, and you
try and do 200 at once, it will take longer than if you do 64 at a
time and let the rest queue up.
