Performance improvement plan

MarcoRossignoli commented 4 years ago

Coverlet performance can be improved in two main areas

Possible plan:

[ ] Create a BDN project with some tests for above main areas to have a baseline

Instrumentation and hits accounting/report generator phases

[ ] Profile cpu/memory consumption to undestand where we spend time during instrumentation/hits report generation phases and optimize code

Performance during test run related to "invasive" instrumentation
[ ] fold adjacents sequence point/branches instrumentation https://github.com/coverlet-coverage/coverlet/issues/307
[ ] undestand if we suffer of false sharing due to in memory array storage and in case found a better structure

I'd like to get started on benchmarking the instrumentation portion.. If no one else has already started on it.

We should add the exploration of P/Invoking of platform specific memory mapping APIs to the list

This issue is stale because it has been open for 3 months with no activity.
