This stuff is really exciting. So I've got a few days to compare a bundled liferay out-of-the-box instance with the one that's enhanced by our company for a certain client. I'll be responsible to analyze the difference in performance statistics by profiling the application. I started off with Grinder and just recently learned about the visually appealing VisualVM.
Apparently, I'll have to collect stats from both of the tools to summarize the overall difference. Ideally, I'd be able to pinpoint the exact methods that must be rewritten to improve the performance. Instrumenting the CPU using VisualVM by limiting it Liferay specific classes seems like a good idea.
Let's see. I'll try to update this post with results, if and when I get them :)
