Dear all, I have finally solved the problem, or better, Zan found what was causing the performance drop, and turned out ICU was constantly querying the FS in search for /etc/localtime which, if not present, was causing a lot of back and forth, degrading performance.
The solution, which has been updated in my ArchLinux kiosk installer for the Pi, was to use timedatectl [1] and be sure such a symlink was there. sudo timedatectl set-timezone "$(curl --fail https://ipapi.co/timezone)" Thanks to Zan in particular, and thanks to this ML too. Have a lovely weekend 👋 [1] https://wiki.archlinux.org/title/System_time#Update_timezone_every_time_NetworkManager_connects_to_a_network On Mon, Aug 9, 2021 at 3:48 PM <z...@falconsigh.net> wrote: > On Sun, Aug 8, 2021, at 11:11 AM, Andrea Giammarchi wrote: > > cog 0.6 and 2.28 (IIRC) were just fine ... the raspbian image from the > wpewebkit site, which has cog 0.6, goes, on the same hardware, more than > twice as fast. > > Meanwhile, weston 9 happened, mesa brought GLES 3.1 in the game, so it's > hard to tell, in isolation, what is causing such drop, but I guess there's > nothing bad in the way I build WPEWebKit there, right? > > Thanks for the reply though. > > > No, you build it just fine. > > Removal of ACCELERATED_2D_CANVAS option shouldn't have any effect on WebGL > content.
