ProcessCaching enabled degrades performance

Weird

When I set ProcessCaching enabled, the time needed to generate a page almost doubles!

Is the meaning of "enabled" here reversed or am I missing something?

BTW, best performance until now with php accelerator (ioncube) +
[Templatesettings]
NodeTreeCaching=enabled
ProcessCaching=disabled

The slowest combination of these 3 parameters gives a whoppy 0.8 sec versus 0.21 sec for the fastest combination with the accelerator (machine used: Dual PIII 1.8 Ghz, SCSI disk subsystem, SuSE Linux).

Template processing still takes the most time (40-60%)

Process caching is not done yet so it's really not adviced to use it. Once it is done (or at least improved) the processing times of templates will decrease significantly.

Tree caching only removes the parsing stage of the template engine, meaing that the template tree is cached as a PHP array ready for use.

Thanks Jan

I hope these speedups make it for the 3.1 release. Right now, around 5-10 pages per second seems to be the limit on recent machinery with ezp. No doubt, load in the future (large collaborative sites) may grow well beyond this for our projects.

Paul,

I'm getting around 70 pages per minute on hardware of a similar spec to yours... I have viewcaching turned on and node and process caching turned off... Are your pages doing some heavy duty work?

Well 70 pages per minute or per second?

Here an average page takes around 0.2 to 0.35 sec to be generated. So something like 100-150 pages per minute is currently a reasonable figure.

But I expect for some sites to go up to 20-30 pages per second, so the (granular) caching efficiency will be very important to sustain such scenarios as it consumes the bulk of the processing time.
