Question

I am using the latest version of Flood-UI on an orange-pi PC (AllWinner H3 SoC + 1GB DDR3) with debian 9.

It works flawlessly, but one things:
When I try to download (through http) a torrent that contains multiple files the max-speed is 3MB/s.
While downloading a single file is 10MB/s.

How to find the bottleneck?
could it be the cpu due to tar-stream?

flood/server/models/client.js

const tar = require('tar-stream');
