It's maximum frequency supported by SPI Flash memory chip without Fast read opcode. Before: $ time dd if=/dev/mtd1 of=/dev/null bs=8M 0+1 records in 0+1 records out real 0m 3.21s user 0m 0.00s sys 0m 3.21s After: $ time dd if=/dev/mtd1 of=/dev/null bs=8M 0+1 records in 0+1 records out real 0m 2.52s user 0m 0.00s sys 0m 2.52s Tested on TP-Link TL-WR1043ND V2.
