If it can, then in addition to searching for and reporting the bug on
the openSUSE's tracker, it would also be useful to search for and report
it against gnome-terminal upstream (on the GNOME bug tracker).

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.
