java - How can I debug pauses in execution in the App Engine production environment? -


when looking @ appstats graphs google app engine/java application, see gaps of seemly unexplainable time between rpcs. in attached screenshot, there gap of 2 seconds between 2 calls memcacheservice.get for-loop. behavior not appear when run code locally. how can investigate cause of anomalies such one, when code running in app engine cloud?

apparently wont let me post images, here's link graph: http://i.imgur.com/bbcxr.jpg

remember app engine shared hosting. while doesn't seem near oversold shared vps hosting still on machine running other sites. if sites code takes on resources possible impact applications performance. not aware of resources app engine sensitive too, @nick-johnson more able tell those. way app engine works prevent of common problems. when @ graph looks me application had grabbed machine gap.
