Created attachment 8503 Diff of the change This patch extends the maximum io range to support values greater than 1000. Such rates are not uncommon with todays NVMe drives. The new maximum value of 32765 is just below INT16_MAX, as int is used to store the value and thus the size is garantueed to be at least 16 bit.
