1% reduction in CPU time per process; or, 1% increase in processes/hr;
or, 1% decrease in delay along some external user-critical path; or,
1% increase in number of simultaneous processes before complaints; ...
Yeah, I get what 1% faster means. I was asking if that's what you meant, as
opposed to some other 1% benefit. (Less memory, for example.)
Although, pedantically, I have to point out that the 1%s you list are not
all synonymous.
