A post was made to gae-appengine-downtime-notify indicating that a change was made to the datastore to reduce the latency spikes that have cropped up since the Sept 13th maintenance.
See this latency chart from a guy who keeps stats on a lot of the cloud providers: http://amistrongeryet.com/op_detail.jsp?op=gae_db_readNonTransactional <http://amistrongeryet.com/op_detail.jsp?op=gae_db_readNonTransactional>The big red line is the 99th percentile datastore non-transactional read time (i.e. it correlates somewhat to the latency spikes). You can see on Sept 13th that latency spikes increased drastically suddenly.. calmed down slightly.. and then proceeded to get worse and worse until just a few hours ago. So, something definitely went well. Hopefully this translates to everyone else getting some respite from these spikes as well.. For my part, I noticed a drastic change in app performance today right after 1:50 PM EST.. Check here to see performance of other services like Simple DB.. etc: http://amistrongeryet.com/dashboard.jsp On Tue, Sep 28, 2010 at 7:41 PM, nischalshetty <nischalshett...@gmail.com>wrote: > Yeah, I've been facing datastore issues as well.
