I wonder if Redis throughput is even a problem in practice. People usually add nodes to get more capacity (memory).

For most use-cases, Redis nodes will saturate network IO before CPU, but it should be noted that Redis is single-threaded so YMMV.

We do heavy pipelining and tend to max out the single thread, so we run multiple redis instances per host.
