  1. Hey,

    Whenever i try to extract multiple .rar files, my PC performance drops down, everything starts to lag, even the simplest tasks, and when i checked CPU usage it was less than 20% ( for WinRar ).

    My PC conf:

    AMD Phenom II X4 940 3.0 GHz
    4GB DDR2
    Asus M4A78 Pro
    nVidia GeForce 250GTS 1GB DDR3
    Windows 7 64 Bit

    Decompressing rar files is going to be tough on your CPU, RAM, and Storage.

    during extraction, the limiting factor will be the I/O consecutive write speed.

    with that CPU & Ram, the only other factor is the i/o performance of your system.

    Make sure you BIOS is set for DMA and is not using PIO

    go to the resource moniter and check the hard drive usage....thatll probably be maxed and thats the reason why you computer lags

    Keep in mind that when you're extracting a rar located on your drive and you're extracting it to that drive you're both reading and writing the the drive at the same time - this will greatly impact your drive performance.
