Comment (by osa1):

 > These are -O vs -O + late-dmd-anal I assume. It'd be worth doing the
 same with -O2 vis -O2 + late-dmd-anal

 nofib runs with -O2 by default. Here's an example command that nofib runs
 to compile of the benchmarks:

 {{{
 ghc-stage2 -O2 -Rghc-timing -H32m -hisuf hi -rtsopts -c Main.hs -o Main.o
 }}}

 with `-flate-dmd-anal`:

 {{{
 ghc-stage2 -O2 -Rghc-timing -H32m -hisuf hi -flate-dmd-anal -rtsopts -c
 Main.hs -o Main.o
 }}}
