Can you post a complete script that is slow for you? If it is a
marker plot and you are using 'backend : WX', it is likely to be pretty
slow because of a problem with marker drawing that was fixed for the
*Agg backends.
Also, are you using wx or wxagg? The WXAgg backend is likely faster
and certainly will produce better output with more features.
After you come up with your test script, please run it with
--verbose-helpful and post the script and the output.
Thanks,
