On Linux I have things set up so that my whole desktop environment is
preloaded into RAM right after the login manager is started.

There is a tool that records file reads. You configure it to run, then
reboot, and login, maybe open some apps you usually use. Next time you
reboot, another tool will read the recorded log and use the readahead
syscall on them. The file list is even sorted by their physical location on
the disk.
