Hi Nick, thank for the response. I know that the memcache response time is not covered by SLA (at least for best effort, dedicated probably have), however yesterday it was very high indeed. Because I'm using ndb and I'm using the default memcache policy my server were very slow (at a certain

Thank Nick and troberti. Great suggestions indeed. And in fact I had both: app stat and cloud trace. App stats record a bit more stuff but I found cloud trace a good compromise for the rough analysis. I investigated a bit more and I found 4 major problem: 1 - memcached layer due to the usage pa
