Wow; that's a really big category.
There are always a lot of variables, but the net result is always
less. It may be 2% 10% or 15%, but it is always less.
If it's less of something I don't care about, it's not a factor (for me).
On the other hand, if I'm paying less and getting more of what I DO
care about, I'd rather go with that.
It's about the cost/benefit *ratio*.
There's also perf vs storage. On a big cluster, you could add a second
Nehalem CPU and maybe get 10-15% boost on throughput, or for the same
capex and opex add 10% new servers, which at scale means many more TB of
storage and the compute to go with it. The decision rests with the team
and their problems.
