Since you try to attach name tags to features, the ARC, bgwriter and 
vacuum-delay work (if that's what you mean with the above) was also 
sponsored by Afilias.

I have no evidence that it actually increases speed or performance, and 
I would even say it reduces total throughput slightly. It makes the 
responstimes more predictable and gives them a lower standard deviation, 
  which is a quality very much appreciated by those who have service 
level agreements saying ugly things like "98% of transactions must 
finish in under 3 seconds" in a 24x7 environment.
