lol, it's a 42MB text file from Google Books Ngrams.
The format looks like this:
$ head words-all.txt
a 14219615690
a! 196012
a" 84
a' 47713
a'0 3036
a'1 4070
a'10 99
a'11 56
I queried it with perl and sort.
$ time perl -wlane 'if ($F[0] =~ /^[qwertyuiop]+$/) { print length($F[0]), "\t", $F[0] }' words-all.txt | sort -rn > qwertywords
real 0m1.915s
user 0m1.896s
sys 0m0.025s
I can't remember exactly which file I downloaded, but according to my notes I got it from here back in 2012 or so.
