When testing is runing.


I found the num of backend pg process as follows (with pgpool) :
[postgres at postgresql1 bin]$ ps x|grep postgres|grep 'postgres: nopass pgbench'|grep -v 'idle'|wc -l
1
[postgres at postgresql1 bin]$ ps x|grep postgres|grep 'postgres: nopass pgbench'|grep -v 'idle'|wc -l
1
[postgres at postgresql1 bin]$ ps x|grep postgres|grep 'postgres: nopass pgbench'|grep -v 'idle'|wc -l
2
[postgres at postgresql1 bin]$ ps x|grep postgres|grep 'postgres: nopass pgbench'|grep -v 'idle'|wc -l
2
[postgres at postgresql1 bin]$ ps x|grep postgres|grep 'postgres: nopass pgbench'|grep -v 'idle'|wc -l
1


But test direct with postgres (without pgpool):


[postgres at postgresql1 bin]$ ps x|grep postgres|grep 'postgres: nopass pgbench'|grep -v 'idle'|wc -l
334
[postgres at postgresql1 bin]$ ps x|grep postgres|grep 'postgres: nopass pgbench'|grep -v 'idle'|wc -l
656


I think that is why the tps (testing without pgpool) is much higher than testing with pgpool .
