It is a geenral problem with the addressbook.  There was a script
floating around at some point to add the indexes to the contacts tables
for MySQL.  I tried googling for it and couldn't find it.  I know it
does really boost performance.

Adding indexes to any field which is used in a where clause should help
performance.  I know caching data is important and it is something we
should look at more in HEAD.
