Sorry for bad format, here is the test results maybe looks better:
Performance
-------------------------------------------------------------------------------------
write read randwrite randread
regular poll BW=3939MiB/s BW=6596MiB/s IOPS=190K IOPS=526K
IRQ BW=3927MiB/s BW=6567MiB/s IOPS=181K IOPS=216K
hybrid poll BW=3933MiB/s BW=6600MiB/s IOPS=190K IOPS=390K(suboptimal)
-------------------------------------------------------------------------------------
CPU Utilization
-------------------------------------------------------------------------------------
write read randwrite randread
regular poll 100% 100% 100% 100%
IRQ 38% 53% 100% 100%
hybrid poll 76% 32% 70% 85%
