Simulation performance

See original GitHub issue

Hi, At work, i’m porting all the repositories to mainline cocotb with python3 and i’m seeing that the performance using python3 is ~4 times worse than python2 For executing the tests, i just changed the PYTHON_BIN env,

I can’t share a testcase now, i will try to recreate this performance issue with a sharable test.

My environment:

debian stretch
python2.7
python3.5
current cocotb master

Thanks

I investigated some more - the graph is misleading, as it doesn’t handle branches well. Here’s a better plot, that draws the branches separately:

The labels are linked to the commits on github.

Edit: updated to use the new data
