Hashing speed and cores

[Ciao121]

Hi,
it seems to me that webtorrent uses a single cpu core when hashing 1 (or more) file(s)? Am I correct?
If the disk I/O it's not a problem... would using multi cores speeds up this process?

[DiegoRBaquero]

Yes, it would. Hashing pieces and files would be done faster

Thanks @DiegoRBaquero,
any suggestion about what to look to implement this in an electron app?
Thank you again.

You would need to reimplemented the hashing either with a different library or by using child processes

Once a time, I actually measured hashing speed and concluded that it wasn't where WebTorrent was spending a majority of it's time. I agree that theoretically this could make things faster, but we'd need to test it before just assuming that it's a win.

The real problem is that programmers have spent far too much time worrying about efficiency in the wrong places and at the wrong times; premature optimization is the root of all evil (or at least most of it) in programming. – Donald Knuth

That said, if someone wants to try something clever and send a PR here, I'll take a look at it.
