Are GAE instances limited to 10 concurrent request?

Question

I\'ve heard from several sources that Google App Engine Instances have a hard limit of 10 concurrent request. I was wondering if someone could clarify what exactly this mean

Answer 1

This has been fixed as of Nov 18th 2013.

The maximum number of requests any GAE instance can process is now configured via the max_concurrent_requests setting eg:

runtime: go
api_version: go1
automatic_scaling:
  max_concurrent_requests: 80

handlers:
  - url: /.*
    script: _go_app

The default is 8 and the maximum is 80.

See https://cloud.google.com/appengine/docs/python/config/appref#automatic_scaling for more info.
