New from PHPKitchen.com:

An interesting article over at the Mambo forums, some benchmarks have been put together comparing a few of the CMS players: Mambo, Xoops, Drupal, e107, Post-Nuke, Xaraya.

Basically, Xaraya gets sliced but I'm not sure the methodology inspires great confidence. [...] 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.

John Lim of PHPEverywhere also throws in his opinions about the situation, stating his ideal setup for a caching system as well (Cache_Lite, conversion to HTML, choosing the right algorithm, and selecting cache invalidation events)...
