pgbench db was initilised with scaling  factor -s 100.

since client count was less there was no queuing of requests in pgbouncer
i would prefer to say  it was in 'passthrough' mode.

Of course pgbouncer is going decrease performance in this situation. You've added a whole layer to things that all traffic has to pass through, without a setup that gains any benefit from the connection pooling. Try making the client count 1000 instead if you want a useful test.
