It largely depends on the GC implementation, especially when you
interpret "time to GC" as "time until you get control back", in
contrast to e.g. "time to claim back (at least) X bytes (because you
want to allocate something)".
There's GC schemes that are usable in hard realtime systems, but I
_very_ much doubt ghc's gc is. If you want to go real-time, you might
want to have a look at Timber.
