New study: Categories vs. Spaces (performance measures)

nicolasraoul — Fri, 04 Feb 2011 08:25:16 GMT

Hello all,I did a lot of performance tests to see how categories can be used in place of spaces,and published my graphs and findings here:http://nicolas-raoul.blogspot.com/2011/02/alfresco-categories-vs-spaces.htmlAny feedback is very welcome :-)Cheers!Nicolas Raoul

Very interesting. But I saw in the small print that you are using 3.2.

I would be very interested in a comparison with a more recent version since Alfresco's performance is radically different post hibernate. And there's a steady stream of performance work going on as well.

I agree with Mike and would like to go a step further. We identified a few places in the Alfresco 3.2 one of our customers is using where non-optimal implementation of Alfresco persistence (not a rant, just a matter of fact for every complex system) is directly related to horrible performance observed in certain scenarios. Especially the aggressive pre-caching/pre-fetching of child content employed is one of the direct reasons why spaces perform as you reported. I'd like to challenge a standard Alfresco with an optimized (read "selectively patched") one, observe the differences and identify potential dynamic bottlenecks for change or introduction of self-adaptability / configurability.

I am planning to do something like this for months now, but unfortunately there are only so many remaining free hours a day to do it.
