Re:Scaling Rails to 125,000 Requests per Minute on Heroku by twic on Saturday August 13, 2016 @06:25AM (#12280981)
The JIT's kicking in is governed by the request count, not the request rate, so this claim is meaningless.

To be precise, in Java 8, if the JIT is not heavily loaded and the code cache has space, then for a method with no loops, compilation will happen when the invocation count exceeds the Tier3InvocationThreshold:

On my machine, with 1.8.0_11-b12, that is 200.
