Databases are, in general, CPU-bound. Most activities are
compute-intensive. Even things you might think would be I/O-bound ...
like COPY ... end up being dominated by parsing and building data
structures.
So, take your pick. COPY might be a good place to start, actually,
since the code is pretty isolated and it would be easy to do tests.
Or am I using a different definition of "compute-intensive" than you are?
