We've been seeing pretty brutal response times intermittently for our app (id: skrit), which I can't figure out. Some more info:
* They're clustered in time: all requests will be slow for several seconds at a time, dozens of times over a couple hours * The long periods of slowness often happen in the morning, although not always, and not every morning * Traffic doesn't appear to be related, and is low (less than 5 requests per second) * It's not instance startup costs. I'm logging when things are imported, and on a small request with no datastore interaction: -- with no startup costs, normally around 30-200ms, spikes to 1300-1600ms -- with startup costs, normally around 1300-1600ms, spikes to 4000-11500ms * It doesn't seem to be related to dynamic get latency or anything else on the serving status page. Initially, we thought it was loosely correlated, but I think those were just flukes. This happens much more often, and for much longer, than serving latency is ever high. * It happens on all requests; I've just given numbers for simplest/ most common request. As far as I can tell, this has only been happening for the past month and a half or so. Any ideas? It's as if we're just intermittently being given really slow serving. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
