DOC: "Accelerated operations" talks about speedup in obsolete versions of Pandas

[wjandrea]

Pandas version checks

• I have checked that the issue still exists on the latest versions of the docs on main here

Location of the documentation

https://pandas.pydata.org/pandas-docs/stable/user_guide/basics.html#accelerated-operations

Permalink to specific line:

pandas/doc/source/user_guide/basics.rst

Line 161 in a89f208

:header: "Operation", "0.11.0 (ms)", "Prior Version (ms)", "Ratio to Prior"

Documentation problem

0.11.0 is more than 10 years old and, of course, before the first stable release.

Suggested fix for documentation

If the important thing is the speedup you get from enabling a feature, then just talk about the speedup instead of when the feature first became available.

Something like this:

    :header: "Operation", "With speedup (ms)", "Without speedup (ms)", "Ratio"

Thanks for the suggestion! While this change would in fact portray the speed difference, the problem with it is that the speeds may become inaccurate overtime, so I think keeping the version number is necessary.

How about updating it with something like: v2.2.0 with speedup (ms) and v2.2.0 without speedup (ms)

I would recommend just removing that timing table section and just linking to https://pandas.pydata.org/pandas-docs/stable/user_guide/enhancingperf.html#eval-performance-comparison instead
