I wrote this, happy for any feedback or to answer any question about the methodology or otherwise.
One thing note is that the headline difference between these instances types is the CPU architecture, the value offered by these instance types is as much about how many IOPS and how much SSD space EC2 chooses to offer for each family, especially for this IO-bound benchmark.
It is entirely plausible that EC2 will offer more hardware bang-for-buck on Graviton instances in an effort to encourage adoption so we can't necessarily draw a strong conclusion about the future of the Arm vs x86 battle on the server CPU front since Amazon is not an Arms-length entity here (pun intended).
- Uehreka 5y agoOne bit of feedback, it’s a good idea to put “higher is better” or “lower is better” on graph axes.
- BeeOnRope 5y agoThanks, this is great feedback that I'll implement next time. You are right that it is not always obvious especially when talking about both throughput (higher is better) and latency (lower is better) in the same post.
- bpicolo 5y agoI might be missing the context, but I think the units on the graphs might be off? Currently "Bytes per second". Guessing there should be a multiplier on that?
- BeeOnRope 5y agoIndeed, the multiplier is 1e9. It was there in the original matplotlib charts, but was dropped in the "chart beautification" process, probably due to the way mpl likes to hide this detail off in a corner somewhere.
