My system has gotten sluggish lately 04 December 2017, 07:02:39 Hello everyone,My install has gotten sluggish over the past week or so and I don't know what to troubleshoot at this point but I think it's something within some software and not a hardware issue. Cycling through i3 workspaces, downloading and installing updates, websurfing, ect. will arbitrarily hang my box for a few seconds to (rarely) minutes, then snap out of it . During hangs music playing from mpd sometimes stalls. Oddly enough, if I play Steam games (Civ5 and L4D2) my computer doesn't stall while in game. This behavior is really inconsistant because I can go for hours with no issue.My CPU monitoring i3block tells me the hangs cause a higher than normal CPU usage (30-60%), but occasionally I'll get a 98% spike while the hangs occur. I tried htop but I'm unable to get to the terminal it's running during the hangs but when I can see it, htop doesn't refresh until the hang stops.I've ruled out faulty memory with memtest86+ and I've also ruled out my HDD with smartmontools and btrfs-check. Booting into the Artix i3 live disc makes my computer run as expected. My install uses the hardened kernel and all software is up to date.As I've said, I have no idea what to troubleshoot at this point to exorcise this ghost. Any suggestions? Thanks, all!
