I understand that Kris is preparing a summary to post to the lists in the next 
couple of days.  The thrust of the work has been an investigation of MySQL on 
an 8-core system, and in particular, how to improve FreeBSD scalability with 
an increase in concurrency.  The preliminary results have been quite 
impressive and show extremely competitive performance when compared with 
another mainstream open source OS.  But I won't steal their thunder, and 
instead encourage you to look out for the posting. :-)
