It seams now that the tests run in the last 2-3 days are more homogeneous. I believe that the high latencies that affected my tests (and caused so different results for the same cases) are the ones that affected the other applications as well. I don't get the 500 error code now and the behavior seams the same through the day.
Unfortunately i have a missing data / corruption problem and it is very very important :( I posted here: http://groups.google.com/group/google-appengine-java/browse_thread/thread/340135d474078313 On Oct 22, 8:59 pm, Andrei Cosmin Fifiiţă <[email protected]> wrote: > seconds :) > > On Fri, Oct 22, 2010 at 8:48 PM, Ikai Lan (Google) > <[email protected]<ikai.l%[email protected]> > > > > > > > > > wrote: > > There are definitely high traffic times and low traffic times, but I would > > be surprised if it had a significant impact on the performance of your > > application.
