Perform a small benchmark, e.g. with /usr/ports/benchmark/bonnie (bonnie =
-d /usr -s <twice as much as your RAM>). Perhaps the write cache is =
turned off, but it's not shown correctly. If your write transfer rates =
around 10 MB/s then the write cache might be disabled. Show the complete =
result and tell also your CPU model.
