My data is from a real-world application. One that gets plenty of traffic. Friendly has served almost 50 million hits since we put it in to production two weeks ago.

It actually happens to be quite a write-intensive workload. We have definitely seen a slow down on writes, but the speed up on reads has more than compensated for it.

We do have more data than RAM. But, most of the data that actually gets read is fresh, so it's hot in cache.

Of course Friendly isn't going to be right for everybody. But, I just want to make it clear that my data isn't from synthetic benchmarks. It's from production.
