Re: Parallel Apply

Hello,

I have a quick question about this work -- is there an expectation of
how quicker parallel apply is, compared to our normal (serial) apply,
for average cases?  Are we talking 20% faster, 2x faster, 10x faster?

(When I say average, I mean not considering fringe cases where the
workload is such that very little paralelization can be done, and also
those where you have a contrived case with one thousand parallel
processes each making progress separately to the point where you get
ridiculously high numbers.  I mean something that can occur in realistic
workloads.)

My point is that if it's 20% faster, it's nice.  But if it's, say, 4x
faster, then it's probably groundbreaking to the point that it may
enable new use cases not currently possible.

Thoughts, pointers?

Many thanks
