Cache performance is around 28-30 MB/s, on a P150 (fairly loaded). It
would make sense that your's is faster, as you have a faster system than I
do and cached xfer test doesn't perform an actual physical read during the
test. Now, the number I stated is from a non-caching test (i.e. -t). I
just performed it a few more times and I actually ended up with about
27MB/s, which for some odd reason is _faster_ than my tests a few weeks
ago. :-)
