- Include fsync in write timing
- No retest option selected
- Record Size 64 kB
- File size set to 1048576 kB
- Command line used: iozone -w -c -e -i 0 -+n -r 64k -s 1g -t 8 -F /backups/f0.ioz /backups/f1.ioz /backups/f2.ioz /backups/f3.ioz /backups/f4.ioz /backups/f5.ioz /backups/f6.ioz /backups/f7.ioz /backups/f8.ioz
- Output is in kBytes/sec
- Time Resolution = 0.000001 seconds.
- Processor cache size set to 1024 kBytes.
- Processor cache line size set to 32 bytes.
- File stride size set to 17 * record size.
- Throughput test with 8 processes
- Each process writes a 1048576 kByte file in 64 kByte records
- Children see throughput for 8 initial writers = 56853.51 kB/sec
- Parent sees throughput for 8 initial writers = 56800.24 kB/sec
- Min throughput per process = 7104.15 kB/sec
- Max throughput per process = 7108.05 kB/sec
- Avg throughput per process = 7106.69 kB/sec
- Min xfer = 1048000.00 kB
- iozone test complete.
