Today, while browsing the net, I new I was gonna have a lot of spare CPU power for some time and decided to use it to do some testing. I didn't want to post the results, there was quite a lot of things running, also some accessing hard drive, so results are not very accurate, but give some insight.
Test set: Chromium sources, almost 1.4GB and over 110000 files, almost entirely text.
.tgz I got from google -
The first test, quick.exe -1.
603.6 MB, 302.x seconds (I didn't write the number down, it's from my memory).
Then FreeArc -m1.
432.9 MB, 363.453 s. Too fast, something's wrong with Quick. Cache? Tested Quick again,
603.6 MB, 228.547 s. this time.
Another test: FreeArc -m2.
331.9 MB / 628.156 s.
Now, FA was going to get beating...The King of efficiency in my another test preformed on application sources, NanoZip -cf.
483.2 MB in 2000.882 s.
Stats given by NZ:
Compression: 3m 2.23s
IO-in: 26m 30.73s
As you see, IO-in is very wrong...
I decided to test it again, I didn't believe that other things I was doing had significant impact on this time, but who knows...Let's do it again. I didn't want to test in exactly the same mode, so I used the second fastest, -cF.
359.4 MB in 3418.375s
Compression: 9m 30.02s
IO-in: 44m 47.16s
Bulat, do you like it?
BTW, Igor's Timer's Process Time showed in the lat test was 122.906 s., ~3% of total time. Totally irrelevant.
