[pgpool-general: 8383] Query cache in shared memory bed performance

[Avi Raboah]

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.
