Ah, chela, you have done well!
Honorable Master beg to offer only one small correction.
Suggest do not assume problem of others same as problem of self.
Sometimes problem need better quality, expensive network, dual
processors, sometimes not.
YMMV is the True Tao.

Master very happy, very happy. Chela is Enlightened. Master also
pleased that chela discover superlinear speedup and more. Suggest chela
investigate memory bound feature of program -- perhaps dual cpu, one
memory bus a problem?
Da "master" feelin' a wee bit lunatic this morning:-) Curiously, I had
just written the following poem and added it to Hot Tea...time to go
look in the mirror and see if those bloodshot eyes are lookin' a little
crazy once again.

Brilliance and Madness
True brilliance, my friend, on the edge of madness lies
So that many a great master has lunatic eyes.
'Tis an irregular stair that mounts to the skies
And thus we conclude: it's crazy to be wise!
