I'm not fully up-to-date with versions etc. but what I've seen is that 
under some circumstances Lazarus- particularly with gtk2- is 
unreasonably slow running over a remote (i.e. networked) X session. 
Speed to a local X session and remotely using VNC is acceptable.

I've recently also noticed that recent versions of Mozilla are also slow 
over remote X but acceptable locally or using VNC. By "slow" I mean 

I've not attempted to raise this as a Mozilla bug or with the distro 
(Debian). Frankly they're both so self-absorbed in their own problems 
I'd not know where to start.
