Re: [Haskell-beginners] Increasing capabilities dramatically increases execution time

Hi friends,

I have encountered a situation in a concurrent program where I see an unexpected, dramatic increase in execution time when I add additional capabilities. On a multi-core CPU, "-N1" is fastest by an order of magnitude and the program increasingly slows for an increasing number of capabilities (still fewer than the number of real cores, of course).
