Concurrent connection count and durable write throughput are different things. And AOF doesn't necessarily mean one fsync per record. The benchmark is taking the worst-case speed of Redis and comparing it to a best-case SQL benchmark. Redis AOF isn't one fsync per record—Redis can use group commit to share fsync across multiple commands. In other words, that could mean a difference of tens of times in your benchmark. I see it differently.
