Interesting quote on performance improvements

Interesting quote from Bryan Cantrill on performance improvements:

"...More than anything, what we (or at least I) learned
from DTrace is that if you want to get big wins, you don't make it
incrementally faster to do existing work -- you eliminate work entirely by
addressing its source higher in the stack of abstraction."
