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.
