I have seen that one, don't you think that the performance difference between an interpreted language vs compiled language comes into play with 10k users?
i'm sure it does. and that's a subjective decision about an objective measure. i've ~ 2K users, with radicale running alongside dovecot/fts-flatcurve/tika+postfix+nginx on 16-core Ryzen with 64GB, and as mentioned -- well enough behaved. could it all be snappier? of course.
