Hello,
question:
What's the way to test compresssion speed of (a new version) from 7-Zip?
I think, there was a small tool - but I don't find it!
http://www.7-zip.org/igor.html
It's possible to measure the execution time with this "timer3.01" tool.
You could compress same file with different versions of 7-zip and measure used time with it.
Thanks for the new alpha - thanks a lot for the effort Igor!
