How to get current busy worker threads which are serving clients ?

[GoogleCodeExporter]

What steps will reproduce the problem?
1. I am running with 50 threads when I am having many request at the same time 
server is taking a long time to response. 

What is the expected output? What do you see instead?

Is there a way I can get current working thread thread count which are busy in 
serving other user so I can increase number of thread according to the 
requirement.

How many cores does the machine actually have?
If it is less than 50 it doesn't make sense from the performance point of view.
Typically the the performance gets worse when more (~) threads than cores are 
running.

My machine have only 2 cores. But all threads are doing only io operation.
Must of the time they are busy in IO.
Main question way is there way or variable which I can use to get current
working thread count ?

Adding one more point I am running server as embedded server inside my 
function. I want to log when my all working threads are busy.

Probably it helps, at least for diagnostic, to define DEBUG - this way you have 
additional information, also about the worker threads.
