Title: Performance differences between OS 3.1, OS 3.2
Post by: Lunda on August 01, 2023, 04:23:23 PM

Is there a way to speed up OS 3.2.2?

First attachment: Comparison between OS 3.2 - P96, FBlit and FText. OS 3.1 FBlit and FText.
Intuition looks pretty good in OS 3.2 - most tests are faster, but ConOutP is pretty slow compared to OS 3.1.

Second attachment: Some cruncher tests are a lot slower in OS 3.2.

What is the root cause of this big difference?

So. The bigger question is. What accelerator and speeds are you you using to perform these tests?
Which libraries are you using for the CPU etc..?

Have you now updated to 3.2.2.1? Any differences?
