Winrar and a E6400

Can someone tell me if I've got this all wrong?

If I want to compress or decompress a large file with winrar it only uses about 6% of the processor and as far as I can tell it isn't very fast this way. Is there a way to utilize the whole CPU so that the job gets done quicker? Why is it only using such a small fraction?

can you not set the priority on that process to high or 'realtime'?

edit: in case you're not familiar...

CTRL + SHIFT + ESC -> right click on winrar process -> set priority

I could, but if winrar is the only thing running besides windows then it's not really competing with any other processes is it?

I'll try it when I get home but it just struck me as so odd that winrar was wasting CPU cycles.

If the archive is very large, and you are decompressing to the same drive that the data is being read from, then you are largely bottlenecked by the hard drive.

Get the latest version of WinRAR, and create an archive of a large file using max compression. This will utilize the CPU much more and will show the app using both cores.

Thanks! I am using an old winrar and had trouble with performance this weekend, time to get the newer version.

Interesting. Maybe that's why archieving and splitting is going slow on my system. I have 3.50.
