I suspect the change in behavior observed by the original poster is caused by a race condition that manifests itself differently depending on the relative speed of different flowgraph threads, to which branch prediction failure rate would contribute. At least that is where I would start debugging efforts. -- Johnathan Corgan Corgan Labs - SDR Training and Development Services http://corganlabs.com
