Well, mine isn't really optimized and it's an older 7200RPM drive on this machine but here are the times: Timing buffer-cache reads: 128 MB in 0.56 seconds =226.55 MB/sec Timing buffered disk reads: 64 MB in 2.91 seconds = 21.99 MB/sec
My file server reports: Timing buffer-cache reads: 128 MB in 0.73 seconds =175.34 MB/sec Timing buffered disk reads: 64 MB in 1.61 seconds = 39.75 MB/sec --- Gordon Johnson <[EMAIL PROTECTED]> wrote: > Hi, > > I'm looking at my hard drives performance.
