Re: Is there any limit on client threads


First I want to say that you will not get any useful data from 250 threads 
talking with Iperf. You will spend the whole time thrashing. However there 
is no limit in the newer Iperfs that I know of to the number of threads. 
There is a maximum based off of available memory, since each thread gets 
its own stack. Also most pthread implementations have a limit but I think 
it is upwards of 1024. Sorry I can't be any more help.
