Unfortunately, I missed your previous message, sorry for this. I processed the CI's trace logs, I got the following performance: bt2 (140.51s) vs bt1 (122.00s). In my opinion, the values are quite similar comparing with my other measurements.

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 and bt2. Although a colleague tried on a recent AMD Ryzen 3700X CPU, and he says bt2 is slower than bt1 for him (36s vs 33s). I'd be curious to know what kind of numbers you get. Simon -------------- next part -------------- An HTML attachment was scrubbed... URL:
