Does Obi 4.1 have better performance than Obi 5.1?

After I moved my project from Obi 4.1 to Obi 5.1 I noticed performance issues. So I made some performance tests with example scene "Benchmark" in Obi assets. I set up same settings ("Time" in project settings too) and I saw that Obi 4.1 is faster in 1.6-1.9 times than obi 5.1.

Here are some photos:
