I want to check some optimizations for Pentium 4 with Hyper Threading. So if you have such CPU, please download file
http://www.7-zip.org/alpha/lzmabench_p4ht.zip
and run a.bat.
You can post res.txt here. Write name of your CPU and frequency from CPU-Z.

Thanks for testing!
It looks like that in HyperThreading mode, decompressing can work 1.5 times faster.
Now I want to check another optimization for Pentium 4 with Hyper Threading. So if you have such CPU, please download updated file:
http://www.7-zip.org/alpha/lzmabench_p4ht.zip
and run a.bat.
My previous posting "Nobody/Anonymous (nobody) - 2007-03-17 11:00"
So this is the same person and same PC testing using your new lzmabench dated - 2007-03-18 01:09.

Thanks for testing, but your system conatins two CPUs. I want to test only one core with Hyper-threding. Purpose of that test is to find some values that allow Hyper-threding threads to work optimally.
Pentium 4 3.0 Ghz. Hyperthreading enabled.
1 Gb of RAM.
