If you direct your requests through a proxy server running on a different 
machine than the server, then you can analyse the proxy's logs.


I suspect that the answers you get will depend in some measure on the size of 
the server machine. A solution that runs worst on a stressed low-end server 
may well perform best on a more generously-proportioned server.

I read a comparison of Postgresql any Mysql (not directly relevant to you, 
but a good illustration). The latter performed better under light load, 
producing shorter transaction times. Under load, Postgresql did better, with 
more concurrent transaction and better reliability under load.
