Read is slower in 2.1.6 than 2.0.14?

Hi, we recently experimented read performance on both versions and found read is slower in 2.1.6. Here is our setup: 1. Machines: 3 physical hosts. Each node has 24 cores CPU, 256G memory and 8x600GB SAS disks with raid 1. 2. Replica is 3 and a billion rows of data is inserted. 3. Key cache
