Anyone use any GTK2 application with Linux Terminal Server?

My is little but has a pour performance.

All GTK2 applications are slow over a network connection, this is not something Lazarus specific.

Well, but i use gnome(nautilus etc), openoffice.org, firefox, an application made with delphi, etc, all with LTSp terminals; Neither application above is a good exemple?

The gtk (1) application don't go so quickilly! Not as the applications not created with lazarus!

The odd thing is, years ago I wrote tappytux to replace the original tuxtype because tuxtype was much slower over the network due to it's design. Tuxtype used SDL with a polling loop. This is fine if you have one copy running locally (and a common game design for that reason) but if you have a few copies running remotely it causes massive interupt locking of the CPU.

I would suggest running PS and checking where the performance is going. Lazarus's event model was much nicer over the network than a loop based poll, if you are seeing high usage of INT in the top output, I would suggest checking your code - you are probably polling something in a loop rather than reacting only to events.

Apparently Nothing wrong!

With LTSp terminals, the click of mouse has a very pour performance.

Install Lazarus
Open Lazarus on a terminal
with F12 change visualization: source editor to Form1 with F12 change visualization: Form1 to source editor with mouse change visualisation: source editor to Form1 with mouse change visualisation: Form1 to source editor by clicking in source editor <Here is the problem>

Is ocour with buttons, etc.
