Throughput test with 8 processes
Each process writes a 65536 kByte file in 4 kByte records
Children see throughput for 8 initial writers = 4251.39 kB/sec
Parent sees throughput for 8 initial writers = 4208.91 kB/sec
Min throughput per process = 530.02 kB/sec
Max throughput per process = 535.52 kB/sec
Avg throughput per process = 531.42 kB/sec
Min xfer = 64864.00 kB
Children see throughput for 8 random readers = 163663.69 kB/sec
Parent sees throughput for 8 random readers = 163434.76 kB/sec
