Doing open-au tests nets no useful data, it's always fast, so just a few examples at the bottom.
Any chance this test was bottleneck on the SDIO interface link speed?
Could very well be. Was tested with a reader that does not support faster than 50 MHz data rate connected via PCMCIA.
But I would expect that at high "open-au-nr" the controller would eventually become the bottleneck and drop speeds to kB/s levels, which didn't seem to happen. I was able to start an --open-au-nr=31 test (which takes quite a while and so I gave up as I'm impatient and was running on battery) with performance the same as the --open-au-nr=7 tests. So either I've gotten the erase block size very wrong, I'm doing something else bone-headed, or the controller is quite good.
Thanks, Andrew
