Is it just memory bandwidth we're hitting? Putting both directories one drive slightly slowed things down.... Same with going to a UP kernel. But nowhere near the differences it made on a similar dual P/200. This system is my main 'work' machine, that isn't usually running fbsd. If anyone has anything they want me to try on it, next time I load it up, let me know.
