I haven't looked at the PowerSDR very much but an application which is required to run in near real-time should:
a) lock itself into memory and, b) if there are enough cores / threads available it should set the affinity of critical threads. It's possible to get the information required to do this correctly from Windows using the memory management API's and the system information API's. The very best way to keep paging to a minimum is to have plenty of RAM. I currently have 12GB but this is a rocket-box development system :) Simon Brown, HB9DRV http://sdr-radio.com > -----Original Message----- > From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex- > radio.biz] On Behalf Of Scott Myers > > A friend of mine and fellow Flex-3000 owner, forwarded to me a little > tweak > to the Win 7 registry which puts the OS kernel into memory and makes it > stop > paging from the hard drive.
