Hi guys, I've decided to convert my servlet/jdo based app engine app to spring mvc (the current app is starting to limit me on doing quick changes/improvements in the code and as I have quite good experience with spring on standard non cloud platforms I've decided to give it a go).
So I've put together project including: - Spring + Spring MVC + Apache Velocity - ehcache + spring-annotations for ehcache + own decorators/interceptors for appengine memcached - objectify - some other util classes ie jsoup, commons (util, baens, logging, codec), gdata The lib directory contains ~42MB of jars (including appengine libraries which makes ~25MB) After deploy, the app takes 50+ seconds to start (sometime the first request get killed after 60 seconds and another app is started) - I've read some articles about speeding up the spring on gae and decided to do another little test. I've created testing app containing only spring + spring mvc with one controller (no other beans, but had to keep the annotation scan enabled for mvc mapping - but disabled the component scan). The controller simply forwards to JSP file with text. Deployed and the page got displayed after 13 seconds. I knew the Spring with all proxies and scanning is not optimal for GAE but I wasn't expecting this at all - it seems like the app have issues with simple loading the libraries as I can see how the memory of instance is growing by 1 MB per second. I've tried to: 1) merge jars into 3-4 bigger ones 2) disable annotations (just for the test as with new spring mvc its quite hard to do some better mapping only in xml) 3) lazy load some spring beans And I can save like 5-10 secods from those 50+ seconds of my startup - is it really so bad for everyone or is there some magic setting? Whats your normal startup time of your spring based app? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
