I looking for software similar to JDownloader or PyLoad. JD is pretty good but use heavy Java and for now have very weak web interface. PyLoad is awesome, include simple but powerful web-UI but downloading 10 files (10 threads each, so summary it's 100 connections running at around 8MB/s all) consume a lot of cpu - it's whole core for me.
Do you know any lightweight alternatives? Aria2c is good for console but I failed to find any good webui, official one is good but after adding more files almost crashes Chrome :)
