Ubuntu Studio Performance Issues
Posted: Mon Sep 09, 2019 8:40 pm
I recently upgraded from KXstudio 14.04 to the current version of Ubuntu Studio, and I'm wondering whether anybody has any insights on the system performance issues I'm seeing.
I'm a very casual user. Most of my computer use is websurfing, e-mail, Libreoffice, and very light gaming like online Flash games. I like to use an audio-oriented distro so that once in a while I can fire up a DAW or some virtual synths and play around a little. My system is a Intel i5-4590 with 12GB of RAM. I didn't have any performance issues with KXstudio; I only upgraded because it was getting harder to keep programs working in the older Linux version. (I know, rookie mistake.)
Since switching I've noticed some real problems. YouTube videos stutter and lag for the first minute or so, whether I'm watching them in Firefox or Brave (I use both for various reasons). Same thing goes for Flash games, although with them it persists, not improving after a few minutes like the Youtube videos do. Any games relying on timing, which is to say most of them, are unplayable. Webpages load/display very slowly. Needless to say, I doubt there's much point in trying to do any real-time audio work when the system freezes and lags like this.
I've run an experiment using an autoclicker in a Flash game. If I set it to click 10 times per second, I see a cyclical (but irregular) pattern. The system is fine for 30 seconds to a minute, accepting clicks at pretty much the full rate. Then the lags kick in, the game slows way down, and the clicks only register one per every second or two, again for thirty seconds to a minute.
Any ideas? Are there even any system logs, etc., I could check to see if something's intermittently starting and stopping?
