There is a data-structure benchmarking kit called "auburn"
    http://www.cs.york.ac.uk/fp/auburn
sadly no longer actively maintained.

One of the things it can do is to generate "datatype usage graphs"
(dugs) for any given abstract datatype.  These record information like
the relative proportions of appends,reads,writes, etc. in a particular
usage scenario.  A series of competing implementations of the abstract
datatype can be benchmarked against a series of randomly generated
dugs.  Furthermore, auburn has an automated decision procedure for
deciding which implementation would be best for your application,
based on the previous benchmarking.
