Hi,
We have been using AppEngine for our production application for over a year now. We are taking little more trafic from last week. We found the number of front end instances that are spun do not follow a paatern. Set min idle instances as 3. We saw 3 resident instances as expected and 6 dynamic instances. But only 3 dyanmic instances took 99% of the requests. The other 3 dynamic instances took 10-20 requests in a day. We monitored the pattern for 3-4 days and we think something is not right..
If the requests are load balanced correctly, why 3 dynamic instances don't serve any requests? We get charged for all FE instances. We stopped the dynamic instances which were taking very few requests and after few mins we found new dynamic instance.. Are we missing anything?
Thanks
Neeli

Unfortunately, your experience is typical. The current GAE load balancing 'scheduler' seems to be very poorly optimized for lower volume applications.
