I have an application made with 0.9.26/gtk2 that is routinely[*] run in 
remote through an ssh tunnel (the X server is either linux or windows 
While it's somewhat slower that running it locally (and by locally I 
mean through vnc, since the machine is headless, so that may mask some 
of the slowness), the difference doesn't seem as dramatic and the app is 
perfectly useable.
The machine where the application is running is a celeron M1.3GHz with 
256M of ram, the os is mandriva 2007.1, kde desktop.
I didn't try to run lazarus itself in remote though, but the performance 
of lazarus/gtk2 on my ageing laptop is very good. In fact, even when I 
was targeting gtk1 due to a memory leak in gtk2 (now solved), I've been 
using the ide compiled with gtk2 long before 0.9.26.

[*]actually the app is just to configure the machine, so it's not run 
everyday, but when it is used it works fine.
