In my opinion, the values are quite similar comparin= g with my other measurements.

Hi Aleksander,

Sorry, I forgot to follow up.  Did you get my last message?

This is the trace we use for benchmarking: https://files.efficios.com/s/pog5raGkBkH63y9

Could you try to compare bt1 and bt2 using that trace?

On the CI benchmark system, we get some similar performance with both bt1 a= nd bt2.  Although
a colleague tried on a recent AMD Ryzen 3700X CPU, and he says bt2 is slowe= r than bt1 for
him (36s vs 33s).  I'd be curious to know what kind of numbers you get= .
