We've noticed really poor memcache response times during the peak of the North American day - 80-120ms for a memcache.get() as fired by NDB (note this is the RPC time as visualized in appstats, so it does not include the deserialization costs).
The performance was so poor in fact that we *disabled memcache* for all of our NDB models. Datastore gets were the same or better in terms of response time - of course, they cost most $$ though. :( This seems to be an order of magnitude worse in terms of performance than when memcache first started. It's too bad because it's hard to untrain memcaching habits, and memcache in general should be awesome. j On Monday, 11 March 2013 16:49:54 UTC-6, Andrin von Rechenberg wrote: > > Are you a heavy user of memcache?
