I recently added a redis cache to my site which caches the full html of a given page including the embedded tracking code for logged out users. Soon after I did this the traffic stats reported in piwik dropped considerably. From what I can tell this shouldn’t be an issue because the code just downloads piwik.js from our piwik server and then calls piwik.php. Has anyone else had similar experiences?
My only other thought for this drop in stats is large latency when connecting with our piwik server. At one point it took 30 seconds for a response from piwki. Is there any way for piwik to report on how long each of its calls make?
