[google-appengine] Spring MVC + GAE = slow startup
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.

[google-appengine] Re: Datastore quota madness
My app is over quotas again.

This is horrible. I'm experiencing this now and no response from Google. It's really sad that Google would have such a flaw in a sensitive service.

But on Google, it takes hours and days for a hosting solution where every second actually matters? Very disappointed...

Re: [google-appengine] Re: Help! please
While it's theoretically possible that Google could have tweaked something somewhere such that your RPC protocol munged Boolean into Boohean, this seems about as likely as me winning the lotto tomorrow (I don't play it). Either: 1) Someone on your team is deploying code changes despite your protestations 2) Your app hit an untested code path that has broken parts 3) You typed in that stacktrace by hand and made a typeo. I'm willing to bet you will figure it out by grepping your codebase (or your version control) for Boohean.

[google-appengine] Re: Spring MVC + GAE = slow startup
Our app is also Spring-based. We did some optimisation about a year ago. Don't really remember how quickly we got our app to start. I think it was in the ballpark of the 13s result you got. 50s is too long. Here's what we've done: * combine our own classes into one JAR * reduce dependencies as much as possible (exclude unnecessary JPA/JDO dependencies if you're not using them) * turn off Spring autoscan (we list Controllers explicitly, but we do use annotations inside the Controllers) * use static instead of dynamic JSP includes when possible * turn on JSP precompilation * there may be a few other things I'm forgetting On Apr 8, 6:16 pm, Tomas tomas.ada...@gmail.com wrote: 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.
