I see that the new FSTSynonymFilterFactory is only "delegated" for Lucene
3.4 and later.
I vaguely recall that there was also a recent improvement in loading of
files for filters.

Actually FST (and SynFilter based on it) was backported to 3.x.

The Lucene FST guys made a big improvement in synonym filtering in
Lucene/Solr 4.0 using FSTs. Or are you already using that?
Or if you are stuck with pre-4.0, you could do a preprocessor that
efficiently generates boolean queries for the synonym expansions. That
should give you more decent query times, assuming you develop a decent
synonym lookup filter.
Maybe you could backport the 4.0 FST code, or at least use the same
techniques for your own preprocessor.

Hi
I have a (23M) synonym file that takes a long time (3 or so minutes) to
load
and once included seems to adversely affect the QTime of the application
by
approximately 4 orders of magnitude.
Any advise on how to load faster and lower the QT would be much
appreciated.
best
