Tony,
I came across the same problem.  I was loading many items to a list view 
and the load time was really bad.  What I found to be the problem is 
that Win32Lib uses LPSTR_TEXTCALLBACK in addLVItem.  This causes Windows 
to call back to Win32Lib to get the text for each list view item instead 
of storing it internally.  Take a look at my SQL utility on the Recent 
Contributions page on the RDS site to see how I got around this.

HTH,

Jonas
