Subjectperformance of vfat versus ext2?
DateWed, 1 Jan 1997 11:20:43 PST
From"Marty Leisner" <>
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.
