Sounds like the original commenter had a reasonable case, but I just don’t think it’s likely to save anything for small sites on traditional stacks. If you are running on i.e. EC2 and RDS instances, you’re not saving anything by using 40% less of the CPU, unless you can actually downsize the instance as a result. Read-only traffic is also not that hard to scale out, but with forums etc, you can be stuck with some legacy systems for sure.
