I flirted with a syctl locking option with 5.2 (or 4.x). When one of the logical processes used the calculation processer, the second logical processor where locked. I turned this off. The result was that the two logical processes started fighting with eachother to who was first in using the calculation processer. Causing a decrease in effency and a increase in CPU temp. I don't remeber any other options. I've stiked with GENERIC ather this. -- Alex Please copy the original recipients, otherwise I may not read your reply. WWW: http://www.kruijff.org/alex/FreeBSD/
