This site includes "Profile Report". It's very interesting and useful!
Then, I compared result of 5/29 with the result of 5/30.
new-order transactions per minute
20050529 1779.41
20050530 2320.41
And I looked Profile Report, Top 20 by Tick.

It is understood that the frequency by which "_spin_unlock_irq" is
called has decreased.
Is there something finding there?
