Hi!
Very interesting link.
Of course read them.
Maybe I dumb but I don't understand why
Engine Utilization (Tick %) = Average 70.0 %
In Engine Utilization (Tick %) only 75 engine.(how in syb_default_pool)
but
ThreadPool : syb_default_pool = 37%
another pool
ThreadPool : syb_system_pool
Thread 1 (Signal Handler) 0.2 % 0.0 % 99.8 %
Thread 82 (NetController) 8.5 % 6.8 % 84.8 %
Thread 83 (DiskController) 3.8 % 0.5 % 95.7 %
------------------------- ------------ ------------ ----------
Pool Summary Total 12.4 % 7.3 % 280.3 %
Average 4.1 % 2.4 % 93.4 %
------------------------- ------------ ------------ ----------
Server Summary Total 2813.4 % 14.8 % 5471.8 %
Average 33.9 % 0.2 % 65.9 %
Adaptive Server threads are consuming 28.3 CPU units.
Throughput (committed xacts per CPU unit) : 51.0
where from there was a difference in 33%???
