thereare some suggestions about the configuration file.  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
externalprocess 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.
