Re: Computer speed

Some of the memory stalls are really branch misprediction.
Improving branch prediction would help reduce effective latency.
Unfortunately, branch prediction for Go is ineffective at best,
as nonstochastic behavior seem inevitable in Go.
So, I hold little hope for branch prediction in Go.
Perhaps, predication (executing both sided of the branch) has promise?
