Poor Core Utilisation



  • Hi,

    I’m running PowerArchiver 2010 11.60 Beta just to try it out, but I’m finding that it is not utilising all the available cores on my i7 (Win7 x64).

    When compressing, it won’t seem to do more than two tasks at once (the others just get placed in the queue) and it only uses 2 of the 4 cores that are available.

    Any ideas why this is, do i need to change a setting somewhere?

    (Compressing both .zipx and .7z)

    it depends on what method are you using… LZMA used in 7z and Optimized ZIPX currently supports only 2 cores. New version of LZMA with proper multicore support is in alpha testing right now, as soon as it is out officially, we will add it.
