Re: performance degradation after launching postgres cluster using pgpool-II

Feeling a little sorry about replying you later.
Then, I want to say so many thanks for this advice, cause we pointed our jobserver to the master directly and then the performance issues resolved. My client is so curious that why pgpool doesn't support so welcome platform like java. Hoping it can get improved in the following versions.
So, besides pgpool, do you have any other solutions for postgresql cluster?
Thanks a lot,Cora

pgpool-II is not very good at handling extended protocol (mostly used

in Java). If you need to execute large updates, you'd better to

connect to PostgreSQL directly. Note that there's no problem that some

sessions connect via pgpool-II, while others directly connect

PostgreSQL.
