Hi Liam, Thanks for the tips. If you remember, though, I previously reported that using :initial-contents (from a list) is slow, in fact, it's slower than setf-ing each element by hand (at least on my system). I don't know (and haven't tried) to use :initial-contents with anything else than a li

Hi Liam, I recently realised that I completely forgot to submit the forms that I used to check where the problem lies with the slow FFT tests. So my apologies, and hereby some very simple forms (should be run in package :gsll). I quickly re-ran them to verify that the timings are still the same
