Expat in HK
Windows 7 Ultimate
C2D 4300 @ 3Ghz (stressed, no errors)
2GB OCZ RAM (tested, no errors)
WinRAR (latest version) set to High, even realtime mode, no difference.

It seems WinRAR never uses more than 10-15% of the CPU when unpacking. It's set on high performance too.

MKVmerge also doesn't use more than 10% when muxing.

Other programs like Mediacoder or running my PS3 Media Server to encode movies, however have no problem pumpin' the crap outta my CPU.

Any suggestions, I don't seem to recall WinRAR having this problem?

Ah, I see. I have an ageing old WD Raptor 74GB.

I was looking to invest in a SSD quite soon, so that may help some.

I'm also testing other zipping programs at the moment.
 
Right, so due to limited I/O performance the program can't fully utilise the CPU.

Got it, thanks guys.
