I don't know what I could do differently - but if I create 100 tracks and do the same thing, PT still processes one track at a time, and very inefficiently.

100 tracks takes over 14 minutes (almost exactly 8.5 secs x 100) and ramps a single core to about 30%, the rest of the cores are idling. Disk writes are ~60MB/sec, so that's not the bottleneck either. Looks like the architecture of PT is the real issue.
