Hello,
I think,
cabal install --reinstall -O2 parsec3-1.0.0.3
should repair this.
I made a tiny benchmark using progression and criterion. https://github.com/kazu-yamamoto/parser-benchmark When I re-install parsec3 with the -O2 option, performance of the tree becomes almost the same. http://www.mew.org/~kazu/plot.png Note that the input file is ASCII. If we use a UTF-8 file, Lazy Text becomes much slower. But this is inevitable, I guess. If people want to compare String and Lazy Text on UTF-8, I will add the case. If people want to campare attoparsecs also, I will add them, too. --Kazu
