Offhand, I don't know why you're seeing such a big difference, then.
Regarding various ways that filesystem is cached in RAM, I consistently
see a big improvement in Racket startup times when there's caching.
Maybe you're using SSD? This is typical for my setup:
[~] time racket -e '(void)'
real 0m1.931s
user 0m0.620s
sys 0m0.132s
[~] time racket -e '(void)'
real 0m0.484s
user 0m0.404s
sys 0m0.076s
[~] time racket -e '(void)'
real 0m0.485s
user 0m0.420s
sys 0m0.060s
[~] echo 3 | sudo tee /proc/sys/vm/drop_caches
3
[~] time racket -e '(void)'
real 0m2.347s
user 0m0.556s
sys 0m0.208s
[~] time racket -e '(void)'
real 0m0.481s
user 0m0.416s
sys 0m0.060s
[~]
Side point: I generally encourage programmers to run GNU/Linux (without
Gnome bloat) as their main workstation, unless they're developing
specifically for Windows or Mac. Windows itself might not be the cause
of your current problem, but it's the cause of similar problems.
