Increase torrent seed preparation speed.

[luckypal]

Hello
WebTorrent library is great.
I am developing Mobile torrent app using WebTorrent, based on IONIC.
Using IONIC, I can access file system using cordova-file-plugin, and I can seed torrent using FileStream.
But it takes much time to create torrent from video file.

I checked create-torrent package in detail, and reduce time to use original pieces from created torrent file. I requested the feature to create-torrent repository.

Anyway, it takes 100+ seconds for about 470MB even I modified creating pieces.
I continued to check webtorrent library and found some codes which takes much time.

It seems like to loads entire file contents from readable stream and store it to this.store.
Why should we load entire file to writable stream on memory?
I think this is not good and there is enough available to reduce time.

Waiting for your reply.
Thanks.

I think if we customize of ChunkStore instead of using memory-chunk-store in IONIC, pumping is not need. Can you provide the similar example?
