i don't know what value shows the -xc oprion, but memory usage in
ghc-compiled program are increased because by default used "copying"
garbage collection algorithm. using option "+RTS -c" will
significantly reduce memory usage, which will make program faster if
it currently needs swapping. you can also force, for example, using of
compacting algorithm when memory usage grows more than 200 mb with
options "+RTS -M1G -c20". see "4.14.2. RTS options to control the
garbage collector" in ghc docs for details
running the profilingbinary (that was compiled with -prof -auto-all)
with the -c option resulted in;
top: showing a max of 161mb memory usage
profiled-graph: showing a peak at a little more than 80mb
i guess these results are more or less normal? It does however mean that
my datastructures are pretty harsh on the garbage collector, doesnt it?
