I tested the latest Intel Threading Blocks optimized version by Vincent Tan vs. the MacParDeluxe 64bit version on the same fileset. The Intel version cuts time in more than half. With the intel optimized version, CPU hovers around 300% (showing 4 near full bars), whereas the MacPar version shows around 30% CPu usage. Also, there is a difference in disk access: the MacPar version writes 15MB/sec spikes, while the Intel version show fewer spikes of around 55MB/sec, reading about 9 MB/sec. I use a decent near empty WD 500 GB 16MB cache drive in Bay 3. Below is verbose output, MacPar version first: $ time ./par264 r -v ../uga-abt-f/uga-abt.par2 par2cmdline version 0.4, Copyright (C) 2003 Peter Brian Clements. par2cmdline comes with ABSOLUTELY NO WARRANTY.

As it turns out, the difference is rather dramatic indeed:
10 vs. 23 real mins!
I tested the latest Intel Threading Blocks optimized version by Vincent Tan vs. the MacParDeluxe 64bit version on the same fileset. The Intel version cuts time in more than half.

With the intel optimized version, CPU hovers around 300% (showing 4 near full bars), whereas the MacPar version shows around 30% CPu usage.
Also, there is a difference in disk access: the MacPar version writes 15MB/sec spikes, while the Intel version show fewer spikes of around 55MB/sec, reading about 9 MB/sec. I use a decent near empty WD 500 GB 16MB cache drive in Bay 3.

Below is verbose output, MacPar version first:

In order to do a "real world" test, many of the .rar parts have blocks missing. I had too few repair blocks, so actually only verification was done. This is heavily disk based. This explains why the results were so close. I will redo the testing properly and report. Greetings, B Wats Hi rAf,

I've made some new tests with intel optimized and with my conf, i get better results... 30% timeless... and no significative improvements with the macpar par2 64bits... How much RAM do you have ? I'll soon update my config with 4 Go and replay some tests... Anyway thanks for testing and sharing results ! it’s strange… I’ve made some new tests with intel optimized and with my conf, i get better results… 30% timeless… and no significative improvements with the macpar par2 64bits…

Anyway thanks for testing and sharing results !

The intel thread optimized version performes even worse than the par executables you provided, which show no real difference (your new 64bit version not shown)
