Very long rar extraction

[KoloheWiz]

It took over 10 minutes to extract a 3.50GB two part RAR file all the while maxing out the CPU and using nearly all the available memory. There were no other programs running except for my startup programs (Norton Internet Security 2013 + ATI Catalyst Control Center + OneNote). It seems like with every update that is issued, the slower and more CPU/Memory intensive the extraction process becomes. I hate having to use multiple decompression programs but may be forced to using the "Win Twins" (WinZip & WinRar) if PA doesn't start functioning better.
