thanks for the feedback, I'm testing with larger files now, 100k+ and
also see APR-JIO-NIO
NIO has a very funny CPU telemetry graph, it fluctuates way to much, so
I have to find where in the code it would do this, so there is still
some work to do.
I'd like to
Hi Filip,
the fluctuation reminds me of something: depending on the client
behaviour connections will end up in TIME_WAIT state. Usually you run
into trouble (throughput stalls) once you have around 30K of them. They
will be cleaned up every now and then by the kernel (talking about the
That's some very good info, it looks like my system never does go over
30k and cleaning it up seems to be working really well.
btw. do you know where I change the cleanup intervals for linux 2.6 kernel?
I figured out what the problem was:
Somewhere I have a lock/wait problem
for example, this
Hi Filip and Rainer,
I found the following info to reduce the TIME_WAIT at windows:

The TIME_WAIT problem is a very common one for Windows NT systems.
Unlike most Unix systems, Windows NT does not have a generic setting
for the TIME_WAIT interval modification. To modify
Hi,

For AIX: To see the current TCP_TIMEWAIT value, run the following
command:

To set the TCP_TIMEWAIT values to 15 seconds, run the following command:
/usr/sbin/no o tcp_timewait =1

Hi Filip,
that's one of the not so nice things with linux. As far as I know it's
not configurable with standard linux. There exist kernel patches for
this and there is an ip filter module that lets you do that, but some
say that module is very bad for IP performance (and high performance
would be
