Hi,
in the case of the /* mapping visiting "/lektor/entry" will trigger a
redirect
response (to add the missing "/" in order to make browser client codebase
correct). This causes two requests per request, double roundtrip etc.
Try redoing the test with "/lektor/entry/" as the URL and see what kind
of results you get.
Hope it helps. :)
