Issue:
TSVNCache.exe makes explorer so slow since version 1.6.1 (fixed yet?)
work-around / Solution:
1. Right-click on your desktop and select "TortoiseSVN -> Settings"
select icon overlays
under status cache, select startup cache, none.
add exclude paths:
c:\*
d:\*
include path can point to your respository.
