Question

I have a web application distributed over different logical and physical layers.

The application is written in php5.3 and uses postgresql version 8.3.

The web front layer has a dedicated machine and is composed of apache htppd 2 webserver running the php engine.

The db layer has another dedicated machine running postgresql. The databases data are stored on machine local file system.

The two layer (web and db) communicate over a 1gbps private network.

I need to setup a execute a performance test on my web application as a whole and the split the test on the single layers (db and web)

Do you know any tool/best practice for such a kind of test?

Any help is appreciated
Thanks
Regards
Alberto
