You might want to look into:

wx.EVT_LIST_CACHE_HINT

I use a virtual list to display data from a database.  When initially 
loading it I get all the appropriate primary keys (have one table with 
about 20,000 rows and it still has very good response) and store the 
result from the select in an attribute of the list, then I have another 
attribute which caches a few pages of the list, so if the users pages 
up/down I don't get have to go to the database all the time.
