I also don't believe Spread has ever been extensively profiled to optimize its computational hot spots.  Spread's primary concern is about giving powerful semantics to users that makes distributed programming easier.  Performance in throughput and latency are very important, but they are not the primary goal of Spread.

Has anyone ever contemplated incorporating spread into the kernel?
