Raymond Hettinger <rhettinger at users.sourceforge.net> added the comment:

I concur.  The source code for set_update() in Objects/setobject.c 
shows that both versions are accessed through the iterator protocol, so 
what you're seeing are the basic performance differences (start-up and 
per-item costs) for genexps vs list iterators.

----------
resolution:  -> invalid
status: open -> closed
