Closed

Description

@diegorusso

Feature or enhancement

Proposal:

In order to improve the JIT memory allocation, we need to know how much memory it uses.

Specifically it would be useful to know the following metrics:

  • code total memory
  • data total memory
  • trampoline total memory
  • padding total memory
  • memory that we free

Also print and histogram of the traces total size.
Use the pystats infrastructure to collect these stats.
