I'm extensively using ListView (several forms with different listviews 
with thousands of items each) with Mono 2.4 under Fedora 11 Beta, 
openSUSE 11.1 and Mono SVN on Ubuntu 9.04 RC. Performance if very good 
and loading a listview with 5000 items will always take less than a 
second, even on an old Athlon XP.

Although, I can remember a recursion problem that affected the listview 
some time ago. I don't have access to the Mono source code right now but 
maybe you or someone else can take a look at the Listview changelog to 
see when was this recursion problem fixed.

Anyway, I'm sure a more recent version of Mono will work. Here are some 
very straightforward instructions to install Mono 2.4 on Ubuntu:
