Fine, this is what I used to do on a DEC Apha, but on my Windows box this does not seem to be the case. I still get only 50% out of the box when checking with taskmgr... What am I doing wrong? Do I need to write "multi-threaded", whatever that is? Doesn't seem to make much sense to me. Two perfectly independent jobs should run just fine along each other, using both CPUs to the maximum... Many thanks for any help!
