A select query over a large table runs very slow because of
the growing number of entries in that table. What different
measures could be taken to improve speed?

Answer Posted / jd

This question cannot be answered with the way it is formulated.

One has to run a trace to figure out why the select is slow.
it could be a lack of index, it could be bad storage
parameters, it could be that the select itself is written
poorly.

Too many problem can be described by this symptom.
