Hi, Would you be willing to compile a kernel with KTR so you can capture some KTR scheduler dumps? That way the scheduler peeps can feed this into schedgraph.py (and you can too!) to figure out what's going on. Maybe things aren't being scheduled correctly and the added latency is killing performance? Adrian
