Comment 10 for bug 423825

I experience the same issue. After system boot, everything is speedy.
Opening some treminals (3-5) with maybe 5-10 tabs each, the system gets very sluggish. Only a few of them actually has a lot of output (tail log files, and debug output from programs).

Just bought an Intel SSD disk, so this should not be a disk IO issue. gnome-termimal process uses 400MiB Memory.
Killing gnome-terminal makes the system fast again.

Eveything is slow, scrolling in Firefox, changing tabs, even writing in this text field is slow.

Running Ubuntu 12.10.
