The FreeBSD-1.1.5 release will contain a new kernel ( I think that it is an entire release.) The new kernel will contain all of the VM enhancements that we talked about a long time ago (1.1 as you know was held up, and many (most) of the VM changes did not make it.) The paging algorithms are vastly improved and lots of things are faster (VM wise.) Our -current has had file clustering for a long time now, and it works pretty good (you really get most of your disk performance now, esp on writes.) The only pseudo-VM related thing that might not make it is the bounce support. It is finally looking better, but I won't make promises yet. An interesting test to demonstrate the new VM performance is to run a process that grabs up all of memory (repeatedly) under X. More than likely, your X will not freeze (waiting for the process to complete.) The results of the benchmark of course might vary because of system configuration... On the original VM code -- the system would not be usable for the duration of the test. There are other neat things that have been added, like better sio stuff, better debugged drivers (incl sound). Generally, you will probably be able to run all of your 1.1 binaries, and you might just go for a new kernel. But there are some new things in the libs too. Please note that even though I am a FreeBSD core team member, it is not my perview to make official announcements -- so take this as a grain of salt :-). John dyson@impode.root.com
