I could envisage most people being able to port their exec and PERL
into the unlang framework.  we havent, so can't give you a direct answer.
however, you COULD do the following

run up a test radiusd server. use the doc/performance-testing document
as a guide to help with the following

1) create a simply PERL that does a DB lookup and return attribute thing
with the list if users

2) create an unlang config that does the same

3) benchmark them


in our PERL we do more than just 'SELECT' - we open a log file,
a debug log file etc and dump stuff into there, we also use other
values from the database to do authorization checks and return
values. depending on the call and request, the return value
changes etc.
