So you got 2x with those optimizations I mentioned?  Nice, did you previously 
get that speed, or?
	Yes ,  the opt.s did get me a ~ 2.5x speed up .  This array (afaicr)
	has never had that high a thruput .  But I am hoping that
	Mr. Dan Williams(et al?) patches will bring this up even more .
	Thank you for posting the optimizations .
