Slow download speed
I have a ddownload premium account and download stuff from time to time. Since the CPU on my Synology DS214+ was always busy, I had slow download speeds because of it. The recommendation from the JD team was to buy a NAS with a stronger CPU. I did that and bought the DS720+.
Last weekend I did a test. I got a speed of about 8.6 Mbps with 7% CPU load on the Synology. Before the whole thing started with CPU usage on the old Synology, I always had a full speed of 12 - 13 Mbps (have a 100Mbit line from Telekom). On the PC I also tested it and there I also had only 8,6 Mbps. Today I tried it again. On the Synology I suddenly reach only 1.3 Mbps and the CPU load was suddenly at 99%. On the PC I still had about 8.6 Mbps. That can't be it after all. There must be an error in the settings. Can someone please help me to finally eliminate the problem. |

@badboyxx: What java version do you use? You can check in MyJDownloader Settings tab or create a log, see https://support.jdownloader.org/Know...d-session-logs and post shown logID here

Ok now it is faster, almost 10 Mbps.
But that is only 80% usage of my whole internet speed. What can I do more to get faster? Or is it a provider restriction as the speed with pc is also not faster? |

@badboyxx: JDownloader shows Mibyte/s, so 10 MiB/s is your full 100Mbit/s. Or do you really mean 10Mbit/s ? that would be 1/10 of your full speed. have you checked speed in browser for same file?

I have a 100 Megabit line. That means that I can get a max. download speed of 12.5 Megabyte/s (one megabyte is technically equal to eight megabits). In the past with my old Synology I had always a speed of min. 12 Megabyte/s. The speed problem began since ddownload offered only the downloads via https.
Tested right now, it is the same speed with browser. |

In that case the issue is with the server (overloaded, bad routing) or with your ISP (overloaded, bad routing) or local firwall/av.
What host do you download from?

Ok I found the problem. Seems that the ISP throttles the line. In my Router I can see that it recognizes only a 78.6 Mbit/s line. I will talk with Telekom.

@badboyxx: Please don't forget that a 100mbit/s line with telekom is everything between 50 and 100. depending on line quality or handshake the actual rate can be lower/higher than 100. You should try to reboot your router and let it do a fresh handshake, that might help.

The ISP did a line reset and my router is detecting 100 Mbit again. I don't know where the problem exactly was but the internet speed is ok now.
