They are actually being started. Like I said, 50 jobs/sec is the peak performance, but I do regularly see 20 jobs/sec. in our labs. Moab Asyncstart probably won't magically make jobs start faster on your system if qrun -a isn't helping a whole lot. There may be other parts of your config that are slowing things down.
