Redis Performance bottleneck is not CPU but Memory Bus speed

http://redis.io/topics/benchmarks states "... CPU is another very important factor ..."

Do the clockspeed math.

Even if the CPU needed 100 cycles for each sorted map update or sorted map sequential read - then a 3 GHz CPU should deliver 30 -million- operations - not 100.000 or 80.000.

Check the memory bus speed - Intel boards have 20 MB/s - AMD only 7 MB/s.

The documentation does mention RAM bandwidth as a factor. Also the math above might not be the case when your map fits in the cache. PRs for improved documentation are welcome in the docs repository. closing.
