In order to test performance with ARMv8 based CPU. Use YCSB to test MongoDB. In 1-16 threads, the performance have a growth curve similar to X86. But in 32 threads or above, the performance reduce and keep at a low level. only in Workload E
So, I want to know why this is happening。 Thanks.

Hi I did building mongod from source. But in Ubuntu 16.04.1 LTS, I found the same problem. |

Seeker MongoDB does not provide an ARM binary for CentOS - based on the environment information you've provided, I assume you're building mongod from source. If you would like to see a CentOS binary included in the platforms actively supported by MongoDB, please open a separate ticket detailing your request. Thanks, |
