On a Dell Inspiron 518 running FreeBSD 14.4, it took 9 hours to install www/firefox from ports.
On that same PC, it took 39.5 hours to build & install www/qt6-webengine, a dependency of x11-fm/konqueror, from ports.
TIFO it's because qt6-webengine bundles its own Chromium, & despite being stripped down, it still took the better part of two days to compile.
Why use something so ancient Vista was the preinstalled OS? Because it works, because it was a gift from one of my customers, and because although an Intel Core 2 Duo E7200 is no speed demon, it's fast enough for everything I need a workstation to do.
BTW, I'm not at all upset at how long it takes to install anything from source. I'm used to it, & it's a conscious personal choice. My first Linux box was an '01 PC running Sorcerer, a now-dead source-based distro.
I'm just amazed at the extreme time disparity between building Firefox and anything Chrome-based.
Also, how many 18 year old PCs can run a modern OS without becoming a Ship of Theseus?
