Thanks, Thats really helpful! Do you mean the SP kernel? I found the SP kernel performed worse than the MP kernel in production.
I also do have debug turned on.. Ok, I shall remove cal...org from our OBSD boxes and from my memory ;) Thanks for the advice, I will do anything I can to stay with OBSD :) Humbly yours, Andy.
