The Benchmark results of MySQL with my plugin

i have got the results of benchmarking MySQL with my plugin these days.
This is a test run for MySQL, there are 6 email buckets and 2 forget buckets.

All numbers are the average for three runs of the benchmark. All times are in seconds.
M    --    denotes using Michael Parker's persistent database connection plugin
Z    --    denotes using Zhang Shunchang's persistent database connection plugin

it costs about 30 minutes for a run of benchmark, i have run 9 times for MySQL. 1-3, using no plugin at all. 4-6, using Michael's plugin. 7-9, using Zhang's plugin.
 i have composed a simple manual for perldoc and  have  solved  the disconnect redifination's problem.  Besides, i will get the results of benchmarking PostgreSQL with my plugin tomorrow. So there is only one thing left:)
