Performance issues (PinePhone, postmarketos, sxmo)
I installed Chatty from the postmarketos repos yesterday, and once I got past the MAM-sync I find the app is very slow. I also use dino (another GTK+3 xmpp app) on the same device, and it isn't a speed demon, but with chatty I find the whole app freezes for several seconds or more on every new inbound message. Sending a message also freezes the app for at least a second.
If I use the app while running top I never see CPU usage over 25% and running iotop I never see much usage at all, so not sure where the stall is happening.
