Title:
  slow terminal output

Status in vte package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: gnome-terminal

  (Ubuntu9.10 using nvidia accelerated drivers)
  When editing a text file in vim, I noticed that scrolling up and down is slow & jerky (i.e. can't keep up with key-repeat speed, does 3-4 updates per second jumping several lines on every update). "top" tells me that no other application is using significant cpu-time. "konsole" on the same system has no problems keeping up with the key-repeat speed on cursor up/down.
  I tested running

  time seq -f 'teeeeeeeeeeeeeeeeeeeeeeeeeeeeeest %g' 1000000

  in both konsole and gnome-terminal with as equal settings as possible:
  * ran in the same gnome-session
  * same window size
  * same font
  * anti-aliased text enabled
  * same amount of scrollback

  and konsole is about 8 times faster. A web search indicates that
  slowness in gnome-terminal has been noticed for several years, so I
  want to make sure this is reported to the proper place.
