There was never a real test for the performance but when you enable the 
checker in the example below (which works only with LuaTeX) the second 
list is slower.

% engine=luatex

\starttext

\testfeatureonce{10000}{\getcheckedparameters[test][xx][a=b,c= d, e = f]}

\enablecheckparameters

\testfeatureonce{10000}{\getcheckedparameters[test][xx][a=b,c= d, e = f]}

\stoptext
