I was referring to the 2000+ qps benchmark result you posted at the beginning of this thread, it's difficult to compare those with backend QPS if those are coming from running ab against localhost. It could be interesting to check what QPS you get when running ab against App Engine frontend urlfetching to your VPS, so we can compare with App Engine Backend and Compute. > The 'wh-test' noop tests > ran 'ab' across a 30Mbit link with fairly low latency to > ghs.google.com... basically the best connection I had available. > > Given that these are high-concurrency tests, I wouldn't expect latency > to be a significant issue - there's a large pending backlog on the > server in each case. > > Jeff > (sorry, I've been travelling in internet dark zones for the last several days) > > -- > You received this message because you are subscribed to the Google Groups > "Google App Engine" group. > To post to this group, send email to google-appengine@googlegroups.com. > To unsubscribe from this group, send email to > google-appengine+unsubscr...@googlegroups.com. > For more options, visit this group at > http://groups.google.com/group/google-appengine?hl=en. > -- Johan Euphrosine (proppy) Developer Programs Engineer Google Developer Relations -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
