I think there's a problem with the number of cores that they report: the vms/containers report 16 cores, while they only have 2. Perhaps -j2 would work better?
Yes :-) cabal build -j1 ....... 7.989s cabal build -j4 ....... 4.736s (I have 4 cores) cabal build -j16 ... 40.510s Today I realized I forgot -O2 yesterday, which cabal uses, I guess. Now cabal does not look that bad. ghc -O2 -j .......... 3.835s ghc -O2 ............. 6.462s -- Wojtek
