Re: Memory usage of BIND process - threads?

Anyway, a stress test will tell... Untested but in 5.1 and earlier I doubt you will see an improvement with threads, with -current using kernel-backed threads this might help on a multiprocesor system. No, this is just an argument to the configure script. The patches in the OpenBSD version of BIND deal with privilege separation, the RNG, and switching to safer string functions. ..also use the kernel's normal port allocator rather than bind's.
