Disregarding File Copy because of the Barracuda, Arithmetic and Dhrystone
because they're cpu bound, FreeBSD seems 2 times slower than Linux in
the essential UNIX measurements. A very wide margin indeed. Admittedly my
one system and some vendor's stats arent to be construed as comprehensive-
but 2 times!?
The other interesting thing is that (C) with 8MB had dd showing 6.99 MB/sec
(really!) but as soon as it was upgraded to 32MB throughput dropped to ~3.7
MB/sec. I have to say that the system doesnt feel any slower and conclude
that it always had a throughput of 3.7. Regardless, this looks like a bug to
me.
Comments?
