I just wanted to ask: is there already some kind of distinction between PHP files involved in tracking visitors and PHP files involved in providing access to the interface (& other background processes like archiving)?
I would like to set up my PHP opcode cache to not cache files related to the interface and background processes but to continue caching the files which are involved in tracking.
This is probably asking for a lot (i.e. too much), but it would be really nice if some kind of identifier could be added to all files involved in the tracking. This way one could configure a negative filter for the Piwik directory but a positive filter for the files with that identifier inside the Piwik directory.
