(You see 20 frames pass before the client process runs) Duh. Ignore my previous message - I should read carefully before writing. You're seeing the scheduling granularity. The originator process is running for twenty frames before its slice is taken away. You need to do something to let those clients run, or better, give the SMP folk a workout. See my last message about passing a token around to ensure everyone runs. -- Peter Dufault (dufault@hda.com) Realtime Machine Control and Simulation HD Associates, Inc. Voice: 508 433 6936
