Re: better performance on poorer machine?

Hi, all.

I found the problem - it was merely a poorly written query, which for some reason was less terrible on my laptop. Looking at http://explain.depesz.com/ helped me solve the issue. Performance is now back to normal.

It seems this was a classic case of pebcak. Thank you for your help and time!

We can but guess, but... Quite possibly your laptop is not actually a
poorer machine for single uncomplicated queries. If it's cores are
faster than the test servers, than your laptop would out-perform the
server for such queries.

Once you get other users starting to run queries as well, turning the
load into a parallel load, the server will probably turn out faster
again.
