Of course it's possible to take everything into kernel, but that might not a good idea since you can also easily crash the whole system and pose serious security issues because kernel trust everything that is considered to be a part of it.
FreeBSD has provided many interfaces that may help out your problem. You may want to take a look at kqueue(2), sendfile(2), accept_filter(9), etc., and consider switching your application model from one to another. Another thing you may have interest is the ktrace/kdump mechanism, as well as ktr that can reveal what exactly the problem is. Please don't hesitate to submit your patch / suggestion to PR system or appropriate maillist if you think there is some *REAL* problem, as that will help the development. å 2005-01-18äç 11:45 +0100ï- Felix -åéï > Hi everyone, > > Doing lot of syscalls interrupts in a soft seems to take quite a long time, > and seriously slow performances.
