Also, wouldn't this create bottlenecks when different processes have to wait for a single kernel thread to finish? I think Solaris has multithreaded kernel support, IIRC. I just find it so interesting that FBSD multitasks and context switches so efficiently and smoothly, and handles such heavy loads, yet the kernel is only single threaded. I just wondered how that was possible. It's certainly a credit to the developers ! Frankly, if it works so well, you have to wonder if stability will be lost finding bugs in the new version if it has multi-threaded kernel support. He, you can't make an omlette w/o breaking some eggs, right? To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
