How Much Do You Save With Ruby 2.7 Memory Compaction?

15-Feb-2020 1556
If you read this blog recently, you may have seen that Ruby Memory Compaction in 2.7 doesn’t affect the speed of Rails Ruby Bench much. That’s fair - RRB isn’t a great way to see that because of how it works. Indeed, Nate Berkopec and others have criticised RRB for that very thing.I think RRB is still a pretty useful benchmark, but I see their point. It is not an example of a typical Rails deployment, and you could write a great benchmark centred around the idea of “how many requests can you process at most without compromising latency at all?” RRB is not that benchmark.
