Query caching Pgpool-II can cache frequently used queries in memory, reducing the load on your PostgreSQL servers and improving response times. This means that when a query is executed, pgpool-II can check the cache first to see if the results are already available rather than sending the query to the database server.

Only in extreme circumstances does the cost (in processor time and I-cache footprint) translate to a tangible benefit - circumstances which usually resort to hand-coded assembly anyway. It shouldn't be 10%, unless it's cache effects. And for leaf routines (which never establish a frame), this is a non-issue.

To be clear, these languages were not designed to be fast or space-efficient, but for ease of use.
