[Pgpool-general] What is the performance penalty of using pgpool

[ram]

Hi,

I am supposed to implement some database replication , in order to have
a real time data backup. 
I tried out pgpool in a test environment and benchmarking with pgbench I
realized that the time for inserts would grow by an average 100% with
pgpool.

But that would mean my application would get thrashed for time. 
I am new to postgres & pgpool ( had been using mysql all the while) 

Can someone guide me is this time difference normal. Where do I look for
any tuning ?
