Hello,
Is there a guide for pgpool optimization?
I am having some bad results with my app queries, but good ones with
pgbench. Let me give an example:
1) With pgbench and SELECT only queries i get:
For pgpool: tps = 644.504312 (including connections establishing)
For stand alone server: tps = 174.842415 (including connections
establishing)
2) With my app most-used SELECT queries i get:
For pgpool: tps = 42.908523 (including connections establishing
For stand alone server: tps = 37.476283 (including connections
establishing)
On 2) there is a small difference. I was wondering if, as pgpool is
running only selects, shouldn't it split queries between 4 servers and
have a tps 4x higher than standalone server? ( i have 4 nodes, that's
why at least 4x higher )
Another question, enabling parallel query would help in this situation?
Best Regards,
