But not nearly as slow as loading 50-60 modules at boot time (on my stable/8 I have 59 right now). When you read one big file *once* you don't have to worry about caching reads. With everything moved to modules, loader does a lot of superfluous disk access, and to remedy this we need smart(er) caching implementation. > /boot/loader.conf (with all modules currently present in GENERIC) may > be instaled by bsdinstall (and may be part of base.txz).

I think we all know what are the benefits of modularized kernels. But before we solve aforementioned problems, it will remain a custom option for advanced users. ./danfe _______________________________________________ svn-src-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
