tina commented on FILEUPLOAD-202:
---------------------------------
It seems the maxThread in resin configuration doesn't work. Because I set it to
256, but when I run 350 thread, it can still run correctly. Before I thought it
is because the first threads finish quickly, another threads reuse them.But I
set the view result in table in Jmeter, and saw each request sent almost the
same time, and the sample time plus the start time is after other sample's
start time. I thought resin should stop processing the request when the number
of threads exceeds the configured maxThread. Do you know the reason why it
still can run correctly?
