Xorg is competing heavily with FF for top hog on my system. In FF I
understand because I had multiple windows (6 desktops) with many tabs. I
know this would theoretically increase Xorg work as well but prior to this update I seldom saw it near the top of “top”

Anyone else pound the crap out of a desktop with FF and see Xorg getting
“fat”?

TIA for any clues or response.

  • Here’s what I see with three FF sessions running at the same time:

  • Thanks Mark.

    Do you happen to know (recall?) if this is more or less in-line with what went on before the latest Xorg fix?

    I may not be doing too badly. I also run 3 users in three X sessions. Two have six desktops and one has two desktops. The last is my “idle”
    user, never doing anything, that sits on tty1 so I can have my active users like they were before the CentOS 6.6 upgrade – the first X session used to come on tty7 and did not screw up when switching run levels to/from 3 and 5 (bug open on CentOS, but I suspect not passed upstream?).

    This is on my home-built box on an MSI 760GM-P23FX MB, SATA.

    From lspci -v, some things that may affect me?

    Do you/anyone think my Xorg CPU usage looks reasonable all things considered or should I be looking for some “tweaks”?

    TIA, Bill

  • Follow-up from my previous post, which as others have noted Goodle is kind enoungh to not let me conveniently see …

    I had forgotten that the longer FF runs in my setup the more CPU it tends to use. And I assume this feeds through to demand on Xorg.

    I stopped FF, restarted and now see very reasonable numbers for it and Xorg, which no longer sits so high up in CPU usage.

    Thanks for passing on the reply, which eventually logged my memory.
