Hi Scott, while I'm sure that most of the FreeBSD admins are aware of "silly" benchmarks where Linux I/O seems to dwarf FreeBSD, do you have some pointers regarding your statement that FreeBSD triumphs for real-world I/O loads? Can this be simulated using iozone, bonnie, etc? More importantly, is there a way to do this file system independently?
