I posted the results of bonnie++ tests two days ago. (fbsd2.txt and obsd.= txt at the bottom) http://lists.freebsd.org/pipermail/freebsd-current/2004-October/040567.ht= ml also I did copies of large mpeg files (sequential read) which were a real pain to process because disks were very slow (as slow as dd tests). I will do all tests that you need to demostrate the problem, just tell me which test you want to do. Now, I'm waiting to S=F8ren. He is the one who can find a bug like this. Regards.
