Performance on Windows

While migrating some jobs from Travis and Appveyor to GHA, I found that windows jobs on GHA are consistently x3.5 times slower. This is surprising, because GNU/Linux and macOS jobs are about the same time. For example:

https://github.com/ghdl/ghdl/pull/1016
https://travis-ci.org/ghdl/ghdl/builds/614458208
https://ci.appveyor.com/project/tgingold/ghdl-psgys/builds/28990530

I think it might be related to https://github.community/t5/GitHub-Actions/Windows-container-I-O-performance-is-slower-than-on-a-lin..., since the tests above are quite I/O intensive.

 

This might be a problem for many projects, specially because Actions are priced per minute.
