[appengine-java] Re: App Engine Really Slow after certain time of no requests
http://code.google.com/intl/en/appengine/kb/java.html#What_Is_A_Loading_Request On Nov 12, 1:48 am, GeneralSlaine lennart.ben...@gmail.com wrote: Hi all, I have had a number of performance issues on initial loading of my app engine application. Part of it is already solved by using Caching. However, my application is still very slow when first loading a servlet after a certain amount of time of inactivity (I think about 1 minute). After this period of inactivity it takes from 3 to 6 seconds to load. Next requests take typically 400 MS. The initial load time is not acceptable for the actual application. Anyone any experience with this? How can I avoid this? I already considered implementing following solutions to keep application / servlet in memory 1/ call application every minute from external application 2/ setup a cron job performing a request every minute to actual servlet I think both are a solution but honestly not my preferred solution as I expect performance from this platform.

[appengine-java] Re: Spring application context initialization on every request
have a look at this link: http://groups.google.com/group/google-appengine-java/browse_thread/thread/603cc766d1e1c3d4/88913abfcb6351e8 On Dec 31 2009, 6:17 pm, Naim mdnh...@gmail.com wrote: Hi, I have deployed a small application on appengine using Spring framework. But I have noticed, if my app does not get any request for a after period of time (10 mins perhaps), all the initialization done by Spring vanishes. To serve the next request, it initializes the Spring application context and all the servlet contexts. At the moment, I am preventing this by running a cron that makes a request to my app every minute. Is there any other way? Am I missing something? __ Naim mdnh...@gmail.com -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.
