You are correct - GET/SET do not require any locking as long as they do not contend and they do not in those benchmarks. You are right that for MSET/MGET you will see lower numbers. But still it will be much higher than with REDIS.

This is our initial release and we just did not have resources to showcase everything under different scenarios. Having said that, if you open an issue with a suggestion of a benchmark that you would like to see I will try to run soon...
