Much lower FLAC encoding speed of v2.1.9 compared to v2.1.6

Open huserbg opened this issue 4 years ago • 2 comments

I am running both with exactly the same settings. The encoder is cuetools with compression level 5. I tested on two different machines:

  1. Core i7-860 under Windows 7 x64 The conversion speed of v2.1.6 is 136x while for v2.1.9 it's 103x.

  2. Ryzen 5 1600x under Windows 10 x64 The conversion speed of v2.1.6 is 225x while for v2.1.9 it's 183x.

I made several tests and the results were consistent. On both machines v2.1.6 is around 30% faster than v2.1.9. The produced flac files are identical (except minor differences in the tags).

This issue seems to be related: #88 I just tested the verification speed of a FLAC album and v2.1.6 is around 20% faster than v2.1.9.

I just tested CUETools v2.2.3 and compared the FLAC compression speed with v2.1.6. Unfortunately, v2.1.6 is still around 30% faster than v2.2.3.
