I used criterion to compare pandoc compiled with parsec2 to pandoc compiled with your version of parsec3. (The benchmark is converting testsuite.txt from markdown to HTML.) The difference was minor:
parsec2: mean: 67.66576 ms, lb 67.56722 ms, ub 67.88983 ms, ci 0.950 std dev: 722.3878 us, lb 323.0343 us, ub 1.356013 ms, ci 0.950
parsec3: mean: 68.20847 ms, lb 68.16387 ms, ub 68.26284 ms, ci 0.950 std dev: 252.7773 us, lb 204.5512 us, ub 325.2424 us, ci 0.950
So, once you release the new parsec3, I am prepared to remove the "parsec < 3" restriction from the libraries I maintain: pandoc, highlighting-kate, filestore, gitit, and yst.
I don't know what the performance of the current parsec3 is compared to parsec2. It would be helpful if you could run your benchmark for that also and include it. If the only issue is performance, I respectfully request that you remove the parsec < 3 requirement even before the new version of parsec3 is released. Thank you. Howard
