I found postgresql running on the multi CPU machine doesn't have better performance than single CPU machine. Can you explain the reason? And how to resolve the problem?
In the Todo list, I read the below message:
Add code to detect an SMP machine and handle spinlocks accordingly
from distributted.net, http://www1.distributed.net/source, in
client/common/cpucheck.cpp
I want to know how to handle spinlocks even if it can detect an SMP machine.
Thank you!
