*Thanks all guys. The problem was solved with Appstats. *
**I thougth appstats need GWT, but I just forgot to add the servlet filter
in web.xml =[ I am ashamed.
With appstats I discover too many JDO data calls being made unnecessary.

When I used the Visual VM to profile the application, it
Glad to hear it! Thanks for updating us and for further validating that
AppStats is a very important tool we should invest more into.

I can't run the profiler, because I don't use GWT on my project. I can just
use the VisualVM.
Do you think the delay to download the xml content response is responsible
for all this CPU usage?

You are doing something wrong.
Looking at my dashboard I have used 1.20 Cpu hours to fetch .5 GBytes of
data from 1464 URLs It looks like I hit my free incoming data quota long
before I hit a CPU quota.
By my calculation you would see the 1 GB data limit on a free account take
up about
But have you called the URL fetch how much times to load all this data?
My response is very short, but I need to call many times.
Maybe this is a problem in Java implementation.

Oh I can. Instead of use Master Slave or High Replication Datastores I use
the undocumented Zero Availability Datastore. rather than storing the data
it just returns 200 success for all queries with a null result.
There is also the option for the Full availability near zero accuracy
datastore
You're thinking of the GWT profiler. We're referring to AppStats:
http://code.google.com/appengine/docs/java/tools/appstats.html
http://code.google.com/appengine/docs/java/tools/appstats.htmlRun that to
figure out where your CPU is going. I'm going to point out that no one in
this thread can
I'll try again this appstats... i tried once but the links are not working.
I thought appstats needs GWT.
I'll post the result. Thanks.
