About the following performance issue: > >> been able to get it to work. The Pro/100B is well supported; it's what I'm > >> using in wcarchive and I haven't had any problems. It consumes about half > >> the CPU time that the de driver does and has about the same level of the kernel is generally compiled with -O , I guess because of fear of broken compiler optimizations. Would it be safe to compile selected parts (e.g. network driver...) of relatively stable code (so that an adequate test period could give confidence on its performance) in the kernel with a more aggressive optimization so as to improve performance of critical parts of the system ?
