Here is some more information

pool_mode                 | transaction

We have transactional pooling and our application is set up in such a way that 
we have one query per transaction. We have set  default pool size to 100.

This is output . As you guys can see active connection are 100 and 224 are 
waiting. We are planning to move default pool size to 250. Please suggest if 
you guys think otherwise

pgbouncer=# show pools;
database  |   user    | cl_active | cl_waiting | sv_active | sv_idle | sv_used 
| sv_tested | sv_login | maxwait

Subject: pg bouncer issue what does sv_used column means

Guys we see spike in pg bouncer during the peak hours and that was slowing down 
the application. We did bump up the connection limit and it is helpful but now 
we  again notice little spike in connection. And one thing that I notice that 
is different is jump in sv_used value when I run command show pools during 
problem times


Can anyone please explain what value of sv_used means when i run show pools;



Regards
Prabhjot
