But these numbers are utterly useless on their own. We need to know
quite a bit more:

1) What are these tests doing? Preferably, share the exact code so
that we can replicate your tests and see the same performance
regression.

2) Full details on the platforms being tested. (Operating system? Word
size (32/64)? Narrow/wide build of 3.2.3?)

3) Preferably, evidence that these tests are a fair sample of
real-world use-cases.

4) Also preferable but not critical: Some indication of which
operations have slowed down, which could then be used to open a ticket
that someone can look into.
