I get, cold cache:
--8<---------------cut here---------------start------------->8---
$ sudo sh -c 'echo 3 > /proc/sys/vm/drop_caches'
$ time guix environment --container --ad-hoc hello -- hello
Hello, world!
real 0m2.815s
user 0m1.852s
sys 0m0.238s
$ sudo sh -c 'echo 3 > /proc/sys/vm/drop_caches'
$ time guix environment --pure --ad-hoc hello -- hello
Hello, world!
real 0m2.656s
user 0m1.733s
sys 0m0.240s
--8<---------------cut here---------------end--------------->8---
and warm cache:
--8<---------------cut here---------------start------------->8---
$ time guix environment --container --ad-hoc hello -- hello
Hello, world!
real 0m1.399s
user 0m1.544s
sys 0m0.104s
$ time guix environment --pure --ad-hoc hello -- hello
Hello, world!
real 0m1.250s
user 0m1.492s
sys 0m0.094s
--8<---------------cut here---------------end--------------->8---
Do you have examples where the difference is significant?
All the best,
simon
