Mark,
Perhaps try these test in a 5.1.19 Wiki given the additional indexing to
improve performance was introduced in 5.1.20 and if there was any change
that could have had an unexpected impact in this area I think it could be
those changes. Keeping in mind the tags field potentially contains multiple
values and if different order so how is this sort indexing operating. I
believe Jeremy's 60K tiddlers were working before 5.1.20 was introduced.
Its great that you are possibly closing in on this. Are you confident your
sidebar is closed and there is nothing that could be interfering? Like my
range of suggestions before?
Regards
Tony
