Under what kind of load would an OpenBSD >firewall's performance suffer due to it being non-multithreaded? Ha. Note: bsd.mp Search the misc archives for "threaded sshd". PF is interrupt-driven inside the kernel and thus faster than any threaded program. Take whoever told you that load of garbled nonsense and push him or her into a midden-heap. That's where it belongs. Threads were invented as a very bad workaround for slow context switching on ancient hardware using primitive OS versions. The people who invented them said they were bad. Any teacher or programmer who says otherwise is ignorant. There's a paper from Berkeley showing how a threaded program can never be fully debugged and should be presumed to be broken, probably fatally broken. geoff steckel curmudgeon for hire, lease, or loan been there since 1966
