Updated JackRabbit M bonnie data

Continuing a previous thread, here is data from a recent RAID6 JackRabbit test.

This is a 24 bay, 24 TB machine, with 64 GB ram, 8 processor cores, 1x DDR IB port, 2x GbE.

[root@jackrabbit ~]# iozone -s 32g -r 2048 -t 4 -F /big/f.0 /big/f.1 /big/f.2 /big/f.3
	Iozone: Performance Test of File I/O
	        Version $Revision: 3.315 $

Not bad … about a 10-15% performance bump for most things, with a nearly 100% bump for writing.

Again, these are 4 threads, each working with 32GB, so 128 GB total data transfer. 2x ram.
