  == Status/Updates ==
+ === June 20, 2006 ===
+ Added new graphs for 0.8 Zipf Workload. I also include Clock-Pro in my simulation.
+ See [http://www.eecg.utoronto.ca/~gokul/soc/zipf-80-rerun.png PNG] and [http://www.eecg.utoronto.ca/~gokul/soc/zipf-80-rerun.pdf
+ Clock-Pro performs the best for this workload which Oystein pointed as being representative
of database workloads. However, the results are not complete since this workload does not
include scans.
