IOZONE writes a 48 Megabyte sequential file consisting of
98304 records which are each 512 bytes in length.
It then reads the file. It prints the bytes-per-second
rate at which the computer can read and write files.
Writing the 48 Megabyte file, 'iozone.tmp'...9.289062 seconds
Reading the file...6.429688 seconds
IOZONE performance measurements:
5418377 bytes/second for writing the file
7828008 bytes/second for reading the file
My Ultra DMA IDE disk generates about 8MB/sec for writing .
Tnks,
Amancio
