Hi,
I ran 100 connections concurrently with pooling and query cache enabled,
and I saw a poor performance which indicting on a very big query waits.
I found in code that there is a locking mechanism when fetching from shmem.
Could you please share why you make a critical section when pgpool trying
to read from cache?
Thanks,
Avi.
