I'd like to know also the signification of the Busy Thread
statistic as for that sample :
Thread pool: Msgs=361536615 Waits=352309147 Misses=2510860082
Max HP Msg=76 Max NP Msg=3174 Current Depth=0 Max Depth=3174
Current High Depth=0 Current Norm Depth=0 Current Threads=48
Max Threads=48 Busy Threads=1
The Busy Threads stat is to show the amount of threads
which are taking CPU cycle at the moment of taking stats.
