Starred it too. Big issue here. - fetch an url + a put() -> 2000 mcycles and more - fetch(100) (+order, filter...) -> 2000 mcycles and more - use import.zip (level = 6 ) -> 2000 mcycles and more - GQL restriction then you need to order by python -> 2000 mcycles and more - etc,...
This quota is really too low : Free Quota HTTP Requests per Day = 650,000 CPU Megacycles per Day = 200,000,000 So the average mcycle/request = (200 000 000 / 650 000) = 300 mcycles. 300 mcycles/req is really low compared to the cost of a basic operation (put, fetch,...). Another things : - I really wonder how it is calculated. As I have always written in another post, it seems that there is no clear relationship between the profiler results and the number of mcycles. You can have a low profiler score and have a warning (CPU quota) and a big profiler score and no warning. So how to optimize ? - It seems that this quota is calculated twice but differently : there is no relationship between the number of mcycles and the Warning (This request used a high amount of CPU....). Example from my log : * 1159mcycles = This request used a high amount of CPU, and was roughly 1.0 times over... * 2030mcycles = no warning ? strange ? no ? If there is no change, my app will be soon offline. Thank you for your answer. Regards On 21 sep, 16:37, Aral Balkan <[EMAIL PROTECTED]> wrote: > Starred it.
