I suspect you might be swapping to the card. One of the easiest ways to
see when that happens if you are using the desktop is to install the CPU
monitor widget, and configure it user=green, system=red, nice=blue and
IO=orange. If you notice lots of orange, its swapping.

If that is the case, you need something better than an SD card, at
minimum a USB 3.1 stick, but an SSD is much better. Alternately a Pi4
with 4GB will eliminate most swapping.
