One easy way to fix the GC time is to increase the default heap size.
./a.out +RTS -A200M
It does make the GC only 1.4% of run time but it increases it overall by 14s.
not surprising - you lose L2 cache locality. try to use -A size that is equal to your L2 cache size -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
