Benchmarks were run on Win 10, 32GB, i7 5820 (6 cores), same machine same month.

  • 12.1 Performance = 2.45
  • 12.2 Performance = 2.28

Complete benchmark results (System Comparisons and Detailed Timings) attached as notebooks.

Anyone else have similar results?

Hi Douglas,

Could you please add these results to this post on MSE. @Anton Antonov has implemented code to analyze the results.

I re-installed 12.1 to get the results data for Anton. In the process I compared 12.1 vs. 12.2. The title for best seems down to rounding numbers, but 2 tests have bigger differences, test-1 and test-11.

One iteration where 12.2 beats 12.1. (12.2 is the top row) Image attached for better resolution.

I have the same issue. Tested on M1 MacBook Air produce 2.68 on 12.2 while 3.11 on 12.1.

Ubuntu 20.04 can repeat this issue.

I have exactly the same issue. Running Mathematica on Intel(R) Core™ i7-7700 CPU @ 3.60GHz this is my result

  • 12.1: “BenchmarkResult” → 2.951, “TotalTime” → 4.69
  • 12.2: “BenchmarkResult” → 2.643, “TotalTime” → 5.23

I’ve found, in general, Mathematica 12.2 to be much slower than 12.1, so that I’ve decided to work on 12.1 version.

Does anyone know how to fix this “bug”?
