[Haskell-cafe] big array allocation too slow?

I'm trying to use newArray to allocate something that has 100M unboxed
doubles. It takes quite a few seconds to do so on GHC 6.10.2. But
doing the same thing (and initialize all to 0) in C returns
immediately. Setting RTS heap size doesn't help. Does anybody happen
to know why?
