I'm running iozone on 2.0.27...
Its a 24 Mbyte dx4/100. On ext2, I get: riting the 25 Megabyte file, 'iozone.tmp'...13.010000 seconds Reading the file...15.290000 seconds
IOZONE performance measurements: 2014942 bytes/second for writing the file 1714480 bytes/second for reading the file
For vfat, I get (on the same disk) riting the 25 Megabyte file, 'iozone.tmp'...16.000000 seconds Reading the file...339.420000 seconds
IOZONE performance measurements: 1638400 bytes/second for writing the file 77232 bytes/second for reading the file
For msdos mounts I get: Writing the 25 Megabyte file, 'iozone.tmp'...12.990000 seconds Reading the file...353.160000 seconds
IOZONE performance measurements: 2018044 bytes/second for writing the file 74228 bytes/second for reading the file
Any hypothesis? I did some performance studies in 1.* and didn't recall seeing this.
