I would like to say that my initial observation and report of the bug 784519 behaviour may be somewhat confusing. That time I had mentioned "constant computational load" as a condition for bug occurrence.
No such a computational load is needed to see the buggy behaviour. The terminals, both Gnome terminal and Terminator, simply become slowly responding after a few days of machine uptime (provided that say about 10 terminal tabs are permanently opened on almost full screen and being used for typical terminal work.) At our department we have a completely identical machine (on hardware side) as the workstation for which I have reported the bug. The twin machine has openSUSE 11.4 with KDE however. I will try to determine if the buggy behaviour is found also there. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-terminal in Ubuntu. https://bugs.launchpad.net/bugs/784519 Title: Natty: performance regression of Gnome terminal Status in “gnome-terminal” package in Ubuntu: Incomplete Bug description: Binary package hint: gnome-terminal I often use to run simulations on my workstations. Such a simulation typically consumes almost all CPU time but only a fraction of memory. Under such conditions previous ubuntu releases 9.10 (Jaunty) and 10.04 (Lucid) were still perfectly responsive, including GNOME terminal. In Natty, I observe very slow switching between terminal tabs when the machine is under constant computational load. Similarly I observe slow response when I want to scroll text on the terminal (using Shift PgUp). It is true that I have terminal opened to its full size but this is the same condition as I used used to apply also on the previous ubuntu releases that were installed on the workstation in the past. Finally I add that (all under the conditions of the computational load): * Switching between workspaces seems to be unaffected by switching to Natty (i.e. as fast as on previous ubuntu releases). * Switching between Firefox tabs also seems to be unaffected and is in most cases noticeably faster than switching between GNOME terminals. * Switching between several GNOME terminals is slow and is often such that I first see just blank terminal and after a delay of a second the text in the terminal finally gets shown. * I am using Ubuntu Classic (No effects), 64-bit variant. * The machine is well equipped: it has an Intel Core2 Quad processor, all its cores running at their full frequency 2336 MHz, 4 GB of memory. * I attach output of the top program to see details of the computational load.
