I feel that ghci code executing speed in guest os is 1.5~2x faster than host os

The code: let t n = do {if n `mod` 100000 == 0 then print n else return ()} >> t (n+1) t 1

any clue?

Speed of the terminal? Cost of syscalls (user/kernel transitions)?

also note that I observed similar things with Win32 code vs. Linux code when compiling stuff unoptimized. See http://www.joachim-breitner.de/blog/archives/358-Building-arbtt-for-Windows.... the first three paragraphs. But I don’t know why that is.
