On a dual-core Opteron 280 with 4G RAM with an LSI PCI-X Fusion-MPT
SAS controller, I am getting wildly uneven results:
tps = 264.775137 (excluding connections establishing)
tps = 160.365754 (excluding connections establishing)
tps = 151.967193 (excluding connections establishing)
tps = 148.010349 (excluding connections establishing)
tps = 260.973569 (excluding connections establishing)
tps = 144.693287 (excluding connections establishing)
tps = 148.147036 (excluding connections establishing)
tps = 259.485717 (excluding connections establishing)
I suspect the hardware's real maximum performance of the system is
~150 tps, but that the LSI's write cache is buffering the writes. I
would love to validate this hypothesis, but I'm not sure how.
