Performance improvement plan

[MarcoRossignoli]

Coverlet performance can be improved in two main areas

• Instrumentation and hits accounting/report generator phases
• Performance during test run related to "invasive" instrumentation

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

There is an issue for it https://github.com/coverlet-coverage/coverlet/issues/808
