[appengine-java] Re: Weird performance problem last 3 days or so
No, I haven't. Interesting idea. I have convinced myself, however, that it is a data store problem. We use the data store currently just to store subscription email addresses, which we use outside the app. Every time someone subscribes, performance tanks, I note the address and clear out the data store, and performance goes back to normal. OTOH, this morning I can't clear out the data store because of: Oops! We couldn't retrieve your list of Kinds. Please try again later. Obviously, we don't need to be using the data store for this (we had plans to use it more), so my next project is to stop using it altogether. Sigh! Thanks for the suggestion, though.

To clarify: yes, I do realize the message means my data store is empty: so I need a new theory of why it took 80 seconds to get a home page this morning.

Re: [appengine-java] Re: Weird performance problem last 3 days or so
I've had similar issues since the past three days. Since I was out on vacation for the week, I'm fairly certain that it wasn't because of anything I changed. The first symptom was when my warmup requests ate up all of my daily quota because I was getting HDEE's all day on Wednesday. This had never happened before. My first suspicion was a long term memory issue with my app since it had been running for a few days. However, since uploading newer versions, I continue to see the same degraded performance. Since late Tuesday, all requests seem to take much longer with a high percentage getting killed due to HDEE. Has something changed on the platform this week? In the mean time, I'm instrumenting for app stats to see if I can get a handle on bottlenecks. ~Michael -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Re: Weird performance problem last 3 days or so
For what it's worth. About the same time, I developed an issue on my dev machine, a (Mac), that seems to be related to the recent Java SE Update 4 release. There a thread on the issue herehttp://code.google.com/appengine/forum/java-forum.html?place=msg%2Fgoogle-appengine-java%2FP6bBEiRB_xQ%2F1stMGk1klSgJ . Any chance the newly released Java update could be impacting performance on app engine (may be a stretch, but thought I would throw that out). ~Michael -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Re: Weird performance problem last 3 days or so
In case it helps you I'll point out that my strategy of deploying the same code under a different appid continues to work, and this morning I switched the domain over to the other appid. This new deployment continues to be lightning fast. The appid I'm using is not new, but has never been used for this app before. I'll also re-emphasize that the new instance has no data in the persistent store, while the other one has a little data that it never uses (long story). -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

I can look into this. Can you reply privately with the real appids for foo and bar?

[appengine-java] Re: Weird performance problem last 3 days or so
Might the difference between your foo and bar deployments be the size of the data set you have for each app? If the fresh install is consistently fine and the old one is consistently slow, maybe you've hit a threshold where some inefficiency in your queries or data handling has started to actually matter. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: Weird performance problem last 3 days or so
Actually, I overstated things. The app actually now uses persistence VERY LITTLE, and only on one page. But the persistent store on the second deployment is empty. It would be strange if this was the problem, but it could be. Thanks again! -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.
