I expect that Python 3.2 will behave comparably to the 2.6 stats, but
I don't have 3.2s handy - can someone confirm please?
I have 3.2 but not 3.3. Can run it later today if no one does.
But better if someone with both on the same machine do the comparison.
The python devs use the microbenchmarks in
Tools/stringbench/stringbench.py, which covers all string operations, as
the basis for improving particular string functions. Overall, Unicode is
nearly as fast as bytes and 3.3 as fast as 3.2. Find/replace is the
notable exception in stringbench, so it is an anomaly. Other things are
faster in 3.3. In selecting the new implementation, the devs also
considered space and speed gains that do not show up in microbenchmarks.
