The wall times of perffncacheencode (see my perf patch) I see here are

             before  with patch 4   number of fncache
                                    entries
Netbeans     4.3     1.0            ~120k
Openoffice   1.6     0.09            ~77k
Xen          0.2     0.009           ~10k

Done on Windows 7 x64.

Pretty faster indeed.
