32-bit Windows has a maximum cache size of 1.2GB.  You really want to
use 64-bit Windows if you are going to serve a large working set out
of AFS via IIS.

That said http://www.secure-endpoints.com/afs/ is currently the Unicode
OAFW pre-release client serving AFS underneath IIS 6.0 on Win2003 SP2 
32-bit.  The underlying hardware is dual processor Pentium III.

As for tuning, just like any other AFS cache manager deployment, you
need to understand your working set.  How many files/directories?
How much data?  Maximum and minimum file sizes?  Etc.  From that info
you can configure the cache manager as per the release notes Appendix A.
