I appreciate this thread has moved on from this question, but I wonder if 
what is being observed is the phenomenon whereby a Search List Extension 
(SLE) included in a given skin is called once for each report within the 
skin, irrespective of whether or not the SLE is used by each report. This 
has certainly been my experience with skins/SLE that I have put 
together/modified. Calling the SLE multiple times is probably not an issue 
in most cases, as the time taken to 'execute' the SLE is usually minimal; 
however, some complex SLEs I have written take a number of seconds to 
execute and this multiplied by the number of reports in the skin can be 
significant. If this is a problem the only real thing you can do is 
refactor your skin/reports to maybe have reports that call the 'problem' 
SLE in their own skin so as to avoid unnecessary calls to the SLE. 
Definitely had to do this with weeWX-WD.
