Hi Tobias,
What's happening when you do an EntryAttributes search, is that each
entry is pulled from storage and all tags processed to build the
attributes map for that entry, then a pattern match is attempted against
the attributes which match your attribute key map. Loading up each
entry and processing all tags on a module which is richly marked up like
the KJV module, for example, can take a bit of time. Compiling SWORD
with optimization can greatly reduce the time. I can also make a
profiling pass on that action and see if there is anything I can clean
up, but generally, for unindexed searches, we try to hit <1sec on
desktops and <3sec on handhelds for a richly marked up Bible like the KJV.
