sebastien commented on JS2-950:
-------------------------------
I was using Jetspeed 2.1.3 in a projet with a lot of hits and I had to maximize
the application throughput. With a lot of profiling of the application, I found
few possible optimizations to the Jetspeed code and one of them was that the
BatchedStatistics class was execively synchronizing. I had the chance to use a
Java 1.5 environnement and I came with a patch using java.util.concurrent api
and removing synchronize blocks.
This patch was tested with jmeter and a profiler and proved to increase the
server throughput. It is also in use in production environement for over a year
without problems.
Since Jetspeed 2.2 now require Java 1.5, I have ported this patch created for
J-2.1.3 to J-2.2. The patch could be integrated in your code and I hope this
could be my first stone to the project.
Please feel free to ask questions about my implementation.
Regards,
Sebastien
