hello everyone, okay if nobody knows an answer to this question i would like to know what appstats is all about if you can only measure (?) the time for a complete RPC request. since i as a developer cannot influence the speed of API methods (e.g. CRUD operations in the bigtable datastore) i am more interested in the performance of my own code. what is the use of appstats if i cannot measure my apps performance (see previous postings)?
