Can you share the benchmark data in a compressed file?

louwrentius commented 4 years ago

I have committed a possible fix to the master branch. Can you verify the issue is solved?

jodykpw commented 4 years ago

Sorry, I don't have those benchmark data anymore, just tried again is fine now.

Thanks for the feedback.
