[jitsi-dev] PseudoTCP performance improvement

#1

Hi,
I've created two small performance improvements in PseudoTCP (see attached patch). This patch does the following:

* Replaces clockThread in PseudoTcpSocketImpl with a thread-pool. That way concurrent connections will use fewer threads.

* Checks logger.isLoggable(Level.FINER) when doing delayed ack to avoid unnecessary string concatenation.

Feel free to use it however you like!

Hi Carl,

Hi,

I’ve created two small performance improvements in PseudoTCP (see attached
patch). This patch does the following:

· Replaces clockThread in PseudoTcpSocketImpl with a thread-pool.
That way concurrent connections will use fewer threads.

· Checks logger.isLoggable(Level.FINER) when doing delayed ack to
avoid unnecessary string concatenation.

Feel free to use it however you like!

Thanks for the patch ! It is now commited and acknowledged on our team
and contributors page.

Eventually we might consider using larger thread pool than 1 or making
it's size configurable.

Also you might be interested in java wrapper for usrsctp stack[1][2].
I haven't measured it's performance yet, but I expect it might be
faster than PseudoTCP. It can also be run on ice4j sockets.
