This is a web app, a mix of read/write, where writes tend to be "insert into ... (select ...)" where the resulting insert is on the order of 100 to 10K rows of two integers. An external process also uses a LOT of CPU power along with each query.

Have you been inserting each insert individually, or as part of a
larger transaction. Wrapping a few thousand up in a begin;end; pair
can really help. You can reasonably wrap 100k or more inserts into a
single transaction. if any one insert fails the whole insert sequence
fails.
