I bet $50 (to Greg) that this is going to go nowhere and that 2 years from now (Fri Feb 4 20:45:24 MST 2000) you will not be able to download or buy a Linux OS (or FreeBSD OS) that can sustain "large" 10 MB/s read or write performance to the native JFS-based filesystem using some native, derived version of JFS to any commercially available persistent hardware endsystem not composed of "RAM". I'll be gracious on the definition of "RAM". As always, I hope I lose :-).
