Some feeling about GAE performance

A web service is deployed in GAE(google app engine). This is the loading test on GAE with different core, concurrency combinations.

1 core, 1 thread, 0.3s per reqeust

1 core, 160 threads, 12s per request

1 core, 150 threads, 8s per request

8 core, 50 threads, 5s per request

16 core, 50 threads, 3s per request

Google App Engine doesn’t support multi-thread of the application, such as multiprocessing in python.

Each GAE supports maximum of 16 cores. If we want to auto-scale, we should read google API and design properly.
