I think you'll be better off with a single table, as you won't have
contention for the index pages in the cache.
One thing to do is to reindex reasonably often (for PG < 7.4) to avoid
index bloat, which will make them not fit in cache. Just check the
size of your index in the pg_class table, and when it gets big,
reindex (assuming you do lots of updates/inserts to the table).
Your table splitting solution sounds like something I'd do if I were
forced to use mysql ;-)
