A correction.. 176K ms, so 176 seconds (not 17,6 seconds).. I think because of parallel execution it must have been calculated so. Maybe it is the calculation in a single cpu system. A single cpu machine would have executed in 176 seconds. About being expensive.. I totally agree to you.. aLi 200

Yes, it's quite trivial for two different http requests to land on two different application instances.

You could just map both domains to one appengine app Id. Then inside your app, make a servlet that intercepts requests, looks at the domain/url and gives different HTML based on what was requested. (Servlets can be mapped to '*' wildcard URLs so that you can access / xyz or slash /foobar/x/y/z

Just to clarify what Jason is saying, the fact that you're seeing two different UserClassLoader instances in those two requests: userclassloa...@1f7cdc7 and userclassloa...@1e6f0ef means that you're actually looking at two requests for two different isolated application instances, with each one u

[appengine-java] Re: issues with compass for GAE apps

Hi Vik. At most a single UserClassLoader is loaded per application instance. Since you're seeing two output lines in your logs, these two requests must have hit separate running instances of your application. In your benchmarking, you need to account for this initialization, i.e. ignoring requests
