[erlang-questions] Efficiency of qlc

When I have a problem with erl_eval, I created beam modules with my
code dynamically using smerl.
But it does not solve all problems, because this _compilation_ is slow
too. But compiled code is fast.
You can collect statistic for each unique query and compile
intensively used ones.
It is also a good idea to use parametrized queries like this:
SELECT * FROM t1 WHERE f1 = ?
It will decrease the count of unique queries.
