Slow Speed Over Remote X11 Session

Hi,

pgAdmin3 cannot be used remotely through X11 forwarding over a relatively
fast Internet connection.

1. http://www.math.umn.edu/systems_guide/putty_xwin32.html and
http://www.straightrunning.com/XmingNotes/
2. Launch pgadmin3 from remote Linux machine (over Putty).
3. Connect to the database.
4. Click the SQL icon to open a new SQL window.
5. Start typing.

*Expected Results*

The UI keeps up with my typing speed.

*Actual Results*

Typing in the SQL window using a remote X session (over a high-bandwidth
Internet connection) is nearly impossible. The UI updates are less than 1
character per 3 seconds. (I can type a smidge over 120 wpm, so 0.3 cps is
painfully slow.)

*Workaround*

1. Open notepad (on local Windows machine).
2. Type a SQL statement into notepad.
3. Copy the SQL.
4. Paste into remote pgadmin SQL window.

*Actual Results*

The UI accepts the pasted content, nearly instantly, as expected.
Kind regards.
