I suggest you try to find queries that are slow and check to see if the
plans are optimal for those queries.
There are some logging options for logging quries that run longer then a
user set limit. That can help finding the slow queries. Just doing some
logging for some typical page fetches often show things that can be done
better. For example, it's not uncommon to see the same information beeing
pulled several times by misstake.
Maybe you can also try something like connection pooling. I'm not sure how
much that can give, but for small queries the connection time is usually
the big part.

I would not do that. In most cases the performance increase is modest and
the data corruption risk after a crash is much bigger so it's not worth
it.
If you have a lot of small inserts then it might be faster with this, but
if possible it's much better to try to do more work in a transaction then
before.
