It measures (if anything) just the buffer cache. Must have been a rather small file. Real disks are < 10 MB/s these days, at least those that are in common use, so it's obvious that the figures are off by at least factor 30. Well, perhaps the file performance tests were run on a memory file system though... :-)) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
