Hello,
We are upgrading in our code the proton version from 0.27.0 to 0.29.0.
While running our unit tests, we found a considerable performance
regression.
We were able to reproduce the regression in a very simple use case.
Please find the code attached.
This test takes 1 ms in the version 0.27.0 and 0.28.0 but it takes 73 ms in
0.29.0 .
Do you know what might be the cause?
We will try to investigate in parallel from our side, too.
Thanks,
Rabih & Ali
