I'm wondering if the lack of slowness I've seen could be due to my simplistic setup: globally set nodejs version, single nodejs version installed, with other tools like git installed by the distro package manager. I also have golang and some other stuff like rclone installed using asdf, but not much more.
Did you also have a similar experience when initially installing node? Did you notice what triggered it or when did asdf start to become slow?
I like asdf and would like to avoid making it slow on my laptop.
Oh and can I safely assume that your home directory is on an SSD and not on an HDD?
