Can you not get the performance information you need from appstats? In appstats you can see how much time each call is using.
A random example from app stats, I can see that a Put cost 41ms of CPU and 620ms of api). According to my understanding - this will only block the CPU of the webserver for 41ms (so it can return to the user quickly), but it will use a total of 661ms cpu time (between the webserver and the various datastore servers) Delete does appear to be quite expensive (I presume as it has to delete the entity, and all its index records) J.
