how much faster do you predict it now will be?

Doing it the OPs way on 1 million records takes 3.3 seconds:

c:\test>junk91 junk.dat
3.25699996948242
([1, 3, 4, 4, 1, 3, 2], [4, 4, 4, 4, 4, 4, 4])

[download]

Same file doing it my way produces the same results in 1/2 a millisecond:

c:\test>junk91-2 junk.dat
0.000479936599731445
([1, 3, 4, 4, 1, 3, 2], [4, 4, 4, 4, 4, 4, 4])

I make that 6,600 times faster. The OPs mileage my vary.

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
