thank you.

I comment this line :
config.cache_classes = false

In the config, And I see it work better.
But, could you answer to this question :


When only one process run, the client wait 0.907 sec.
When 2 process run together, each client wait 1.705 sec.
When 5 process run together, each client wait 4.073 sec.

Whereas ruby take 0.760 sec each time, for all process in all
configuration.

Why?
