Currently I've tried to optimize the
receive
function. I might look atsend
later.The correctness should still be checked before this can be merged.
This pull request includes:
unsafeRxMap
andunsafeRxGetMapping
).rxqDescriptor
function from theRxQueue
record and write it as a separate inlinable function.Now the
go
loop inside thereceive
function uses unboxed operations almost exclusively, which means that no garbage gets generated. The only non-unboxed operations are due toIORef
s. That might be a further opportunity for optimization. There is also allocation for thebufPtr
that is consed to thebufs
list, so using a mutable vector for that would probably also improve performance.
