I've tried db_bench in the rocksdb on blobfs, but didn't get performance improvement as expected.
Compared with NO_SPDK, insert increased 70%, readwrite increased 28%, but overwrite decreased 38%, randread decreased 48%.
(the attached pic is the detail results.)
Is it a normal result or is there a way that we can get a better result by adjusting some parameters?

PS, here are the environment:
Storage: P3700, OS: CentOS 7.3, gcc: 6.3, Keys: 16B, Values: 1000B, Entries: 500M

Thanks,
Yun
