I wonder if there is a way to work out a base line value. Benchmarks
could then look for multiples of this.

So, something like time to create a big list (for CPU), and time to read
a defined file (for IO). Then you could say "this file should parse in
1x IO base-line + 10x CPU base-line.

That way the bench marks could become part of the test set. If things
got significantly slower, tests would fail.
