Ubuntu – Discord suddenly very slow

16.04

I updated some programs yesterday, and Discord is suddenly very slow and stuttering. It is only that program, nothing else is affected. The size of the window is a factor as well, if I resize it to be small, the window runs smoothly. This is especially notable if someone posts media in Discord such as a Youtube-link, where it will run very slowly as long as it's windowed in Discord. However, fullscreening it will make it run at full speed with no problems.

Where would I start to find out why it's suddenly running so slow?

I did not find what caused the slowdowns, but I did a manual downgrade to temporarily fix the problem.

I removed the program through Ubuntu Software, and installed it manually using a .deb of a earlier build, which was available on Discord's own website. The slowdowns are completely gone. I have reported the bug to Discord through their own channels.

EDIT: Discord has 0.0.8, which was a version before the slowdown troubles, on their site: https://discordapp.com/api/download?platform=linux&format=deb

Ubuntu – Ubuntu 16.04 Very slow boot

I had partial success today. One of the most helpful diagnostics is:

systemd-analyze plot > <some_file_name>.html

Use a browser to view it. This made it clear that powerd.service was the biggest problem. It never actually got started, and the boot just waited until it timed out. Since powerd.service never really started, I figured I wouldn't miss it if it wasn't there, and, sure enough, I removed the powerd package and now the boot time is just slightly over a minute(vs. 3.5 minutes with it).

I really don't know if powerd is supposed to be running on my computer(a laptop) as it seems all the documentation I can find describes it's use for a phone. Anyone know if this is true?

The next slowest service to start is wicd.service. This actually gets started, but takes about 36 seconds. Not sure why, but that is the next thing I will look at.

Ubuntu – Firefox very slow to start

I admit this to be an oddball answer but here I find I need to reboot my DSL Router when connectivity to the outside world slows down: Firefox, ansiweather (Terminal-based weather utility), etc. To me everything in the Router's web pages look fine -- 40-50% memory usage, etc. Boot the Router and I'm back to full speed for another month or so. HTH.
