Shasoosh Posted August 28, 2007 Share Posted August 28, 2007 when i extract a big file (1 g or more) i've noticed that winrar only uses 8-12% of my cpu, is there a way to force him to use more cpu and by so it will finish more quickly?

0 The2 Posted August 28, 2007 Share Posted August 28, 2007 Maybe your hard drive is too slow? Try extracting from one hard drive to the other if you have two. Link to comment Share on other sites More sharing options...

0 The2 Posted August 28, 2007 Share Posted August 28, 2007 WD 320GB 16MB SATA2 7200 RPM - WD3200AAKS - too slow? Hm...that's strange. I know it's a long shot - have you tried the latest version? Link to comment Share on other sites More sharing options...
0 Shasoosh Posted August 28, 2007 Author Share Posted August 28, 2007 on with the latest.. on other systems winrar takes 100 cpu? Link to comment Share on other sites More sharing options...
0 GreenMartian Posted August 29, 2007 Share Posted August 29, 2007 Yeah. It utilises 100% of my CPU. Although I think that may be because my PC is about 7 years old When you say slow, what do you benchmark it against? How does it perform when extracting a file HALF the size? Could still be a HD speed limitation. Can't make it spin faster than what it's designed to :) Or it could be a Vista thing, who knows? You dual-booting?

0 gnuman Posted August 29, 2007 Share Posted August 29, 2007 You could right click on the process and give it higher priority. That should improve the performance. Also if you are extracting 1gb files, your HD is probably quite fragmented. Link to comment Share on other sites More sharing options...
0 Shasoosh Posted August 29, 2007 Author Share Posted August 29, 2007 i dont have xp here... its not slow as in "dead slow", maybe its the way that winrar programed i've tried it gnuman, it goes up to 23% and its a bit faster but still not using the cpu full capacity Link to comment Share on other sites More sharing options...
0 Shasoosh Posted November 29, 2007 Author Share Posted November 29, 2007 I'm bumping this topic with a new pic hopefully to get some answers. maybe a winrar alternative? Link to comment Share on other sites More sharing options...
0 GusValentine Posted November 30, 2007 Share Posted November 30, 2007 For an alternative, nothing to lose by trying 7-Zip http://www.7-zip.org/ Try 7-Zip 4.56 beta (2007-10-24) Even though it says Beta, it's still very stable; has been for me anyway.

0 Gangsta Posted November 30, 2007 Share Posted November 30, 2007 7-zip is good. However, I actually like jZip (uses 7-zip compression tech, etc, and can open all the same files) because it seems more like a release product. I dunno, I just don't like the feel of 7-zip that much... Link to comment Share on other sites More sharing options...
0 kcjuggalo Posted January 17, 2008 Share Posted January 17, 2008 I'm new here but this subject is why I joined... I have a problem that is similar in that the amount of CPU used to extract files will change and I'm not sure why so maybe someone here can help me:) My problem is that I can extract a file (using winrar 3.7) in 4 seconds flat. Meaning when the little box pops up for winRAR when the counter hits 4 seconds its done (on a 700MB file)... but sometimes it will take 30-40 seconds for a 700MB file and for a long time i've just chalked it up to different compressions or me doing other stuff on the hard drive. But today i found something that if I take an archive and try to extract it and it takes 30-40 seconds it only uses about 6-8% CPU in processs explorer. HOWEVER. If I delete one file of hte archive and repair it with quickpar and then extract the same archive it will extract in 4 seconds like the rest of them and the CPU usage is at 25% I hope that makes sense to someone... Basically does anyone know what would cause a quickpar repair to change the speed of the extraction or CPU usage of winrar? Thanks. Link to comment Share on other sites More sharing options...
0 frogger Posted May 2, 2009 Share Posted May 2, 2009 huge bump, i know, but i was researching this problem myself. I upgraded winrar to the newest 64bit native BETA. That brought it up to about 40% and i did a benchmark and a couple calculation, and the rest can be chalked up to HD performance. I didn't think it would be a limiting factor either, but it is.

0 soldier1st Posted May 2, 2009 Share Posted May 2, 2009 perhaps for those who have a dual core you could turn the multithreading option on, perhaps that will speed it up, also if the virus scanning option is turned on that could slow it down.
