It could also be all the usual things that affect performance. Are your
queries using indexes where it should? Do you vacuum analyze after you
have updated/inserted a lot of data?

It could be that some of your queries is not as efficient as it should,
like doing a sequenctial scan over a table instead of an index scan. That
translates into more IO needed and slower response times. Especially when
you have more connections figthing for the available IO.
