Yeah, I refreshed pages over and over, and almost 1 out of 10 requests where 'startup' priced. Which doesn't correlate to the response that if you keep the instance up it will not open another instance. My guess is multiple servers just get the request maybe with slight preference to use an alre

Hello Jason, I am also using spring and I experience the same issue. Initializing Spring FrameworkServlet takes about 15 seconds. Going back to plain old servlets sounds like a bad idea to me. Isn't there any other way to speed this up? Maybe using memcache? Cheers, Tobias On Oct 23, 5:53 pm

Keeping steady HTTP traffic does not work either. I have a script which 'http pings' my application every 30 seconds. Yet my app-engine instance experienced 70 spin downs yesterday alone! I am REALLY looking to this update - until then I'd highly recommend staying away from Spring! On Oct 21, 6:

Aside from keeping steady HTTP traffic to your site, I'm afraid not. But as I wrote in my last post, we're making updates over the next few releases to drive this startup time lower. - Jason On Tue, Oct 20, 2009 at 2:06 AM, Marcel Overdijk wrote: > > Is there any other way to keep an instance "w

Java startup cost is way too heavy and unusable on appengine. I'm considering learning python now for the time being. On Oct 19, 1:58 pm, "Jason (Google)" wrote: > To answer your question, no, having a cron job run every minute to keep an > instance warm will not work. If all application instanc

To answer your question, no, having a cron job run every minute to keep an instance warm will not work. If all application instances have spun down, then a fresh HTTP request will require a new instance to be created, which will incur the startup costs. - Jason On Fri, Oct 16, 2009 at 6:45 AM, To

In general, and as the numbers that you've shared also back up, spinning up a new instance of a Java application does take more resources, both CPU and time, than starting up a new Python application. We are making back-end improvements in the next couple of releases to improve these times, partic
