Thanks for your help. that sounds promising.
One question I have is how crashing instances are handled: If I get a warning message like this: After handling this request, the process that handled this request was found to be using too much memory and was terminated. This is likely to cause a new process to be used for the next request to your application. If you see this message frequently, you may have a memory leak in your application. will the instance spin up a new process within milliseconds? Yes I have a lot of datastore reads, but this is mostly because all queries are different and caching the responses wont give me much. I use memcache very heavily. I'm also working on a backend for all these different queries to be served out of RAM...
