OK.
I was using GENERIC vs GENERIC from RELENG7 and RELENG8 from
today. MAC is in by default in RELENG_8
One bright spot on the file IO is the AHCI driver when the test is
done with much larger data. Instead of 3G of test data I ran 6G....
I am guessing AHCI does better due to the command re-ordering
RELENG8
Running the test with following options:
Number of threads: 16
Extra file open flags: 0
128 files, 48Mb each
6Gb total file size
Block size 16Kb
Number of random requests for random IO: 10000
Read/Write ratio for combined random IO test: 1.50
Periodic FSYNC enabled, calling fsync() each 100 requests.
Calling fsync() at the end of test, Enabled.
Using synchronous I/O mode
Doing random r/w test
Threads started!
Done.
RELENG8 (AHCI)
