1. Might readMVar really be computationally expensive under heavy load, (with all it's wonderful blocking features)? How much (approximately) more expensive, comparing to a assembler's "mov"?
Probably 10-100 times more expensive than a mov, depending on the cache state.
many years ago, with ghc 6.6 and duron-1000, i had million or two of withMVar per second. anyway, this sort of things is easier to test herself -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
