I did each test only once, and the test lasts only a few seconds, but here are the results: Without keep-config (i.e ONFI timings) : # time dd if=/dev/mtd3 of=/dev/null bs=1M 32+0 records in 32+0 records out real 0m 3.54s user 0m 0.00s sys 0m 0.26s With keep-config (i.e bootloader timings) # time dd if=/dev/mtd3 of=/dev/null bs=1M 32+0 records in 32+0 records out real 0m 3.77s user 0m 0.00s sys 0m 0.21s I.e we are apparently slightly faster with the ONFI timings. However again, the test duration is very short, and I didn't repeat the test several times.
