Whats new in GnuGk 3.5 ? Part 3: Performance

To avoid the performance hit that happens on Linux when your GNU Gatekeeper gets swapped out on a busy server, GnuGk 3.5  has a new command line switch to lock GnuGk in memory (--mlock).

As a tool to allow you to better monitor your call volume, the call statistics on the status port will now show the peak number of calls in addition to the current load. This is an important piece of data to plan socket and thread allocation for your configuration.

GnuGk 3.5 will now also run on certain Linux server virtualization platforms that don't give GnuGk full control over thread prioritization, even when running under the root user. Now you can turn off setting the proxy handler thread to high priority and GnuGk will start as it should. Use the ProxyHandlerHighPrio switch if your GnuGk dies on startup with a PTLib assertion "pthread_setschedparam failed".


If you run a high load GnuGk installation or if you are concerned about performance, please contact me to have a chat.
