I was able to get buildworld compiling ok and here are the results:

4BSD        ULE.13        ULE.7
13:24.73    13:44.28    13:38.85

Only a 1.75% difference when the slice value is set to 7.

If anyone has suggestions for other benchmarks to run for different
workloads to test, let me know and I'd be happy to run it for the
above 3 configurations.
