An interesting article over at the Mambo forums, some benchmarks have been put together comparing a few of the CMS players:
Basically, Xaraya gets sliced but I’m not sure the methodology inspires great confidence. [*Note: we had a candidate come in to interview for a lead programmer position recently and the chap didn’t know the word ‘methodology’, he was sure it was ‘methology’ ;-)]
It’s claimed Xaraya took 42 seconds to load a page which sounds a bit Olympic, and e107 (never heard of it) is touted as the big performer. Would be nice to see of few of the other players put through their paces.
While the graphs are nice and probably about as misleading as all graphs, what I liked is the benchmarks compared server load sustained over a given test period, ie, indicating which software was more CPU intensive and likely die under duress.
Maybe e107 had the smallest impact on the server but maybe that impact is mirrored by a modest feature set? Can’t really be scientific. Derick Rethans latest xDebug usefully measures memory usage, this will shed light if you want to run your own tests.
