I had a bit weird experience with this... So I wrote app (http://analytics.bugaco.com) that runs on App Engine. Than I looked at the request logs to see how it is running. Request logs suggested that I'm using a lot of CPU time on hitting the home page, but after that CPU time significantly decreases. It also had annoying red flag suggesting that servlet is using excessive resources and that I need to optimize it. Testing a bit, I noticed that pinging lets app be warm, and I had cron doing the pings for a few days; while also noticing that it does not do anything useful
Conclusion: 1. If log files don't suggest that you are better off pinging people would not ping 2. It is stupid that google counts warming up your app toward CPU time (leading to profiling, that leads to pinging) 3. It is very stupid that applications can not denote 'keep this code path warm/cache it/or something' that will allow new users not to give up on the up until they get first response. So, as a conclusion, I think AppEngine is AWESOME. And I also think it SUCKS. I love SDK, ability to deploy and test and use all the cool things. I don't like the idea that it can not serve a (entry)page in 3-5 seconds as I think that it leaves bad taste in users mouth, and consequently bad taste in developers mouth. Finally, I am not sure I'll use AppEngine for developing other applications as I'd rather go with paid hosting that provides some level of performance on serving pages. I think Google would win a lot of good will if they at least provide quick serving of static resources. One may wonder how to do that, and given that they have all those yaml files there may be yaml file that specifies a warm static resource. This would decrease a need for pinging your app as it would allow user to hit entry page, and google to pre-cache app much easier. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
