Many of the best Linux devs these days work for companies and organizations that are in the business of selling or using big iron. They have people on staff who test the kernel and whine if it fails to run well with a ton of memory and a gazillion CPUs (plus people who actually fix it); it's not their job to care about low end systems. However, you don't have to be a VM hacker to run a bunch of benchmarks to compare performance and point out regressions. People tend to listen if you offer some hard numbers instead of a rant about how nobody cares about the low end.
