Default Why my download speed is restricted to 11 mb/s

Hello,
It's strange, I have fiber optic broadband 100 mb download/100 mb upload, but I never can download more than 11 mb/s.

I tried different mirrors with different files, to test the speed, but always is limited to 11 mb/s

How may break this limit?

I did a test to my connection and it is working fine, 100 mb/s download and 100 mb/s upload.

Any idea to solve this?
Cheers

@mrmister: Sure you have 100mbyte/s and not 100mbit/s ?
11 mbyte/s sounds abour 100mbit/s connection. Else you would need a full sync 1gbit/s connection. and normally speeds are given in mbit and not mbyte.so most likely 100mbit/s up/down connection

Yes, megabytes.

My connection speed is broad band:

100 megabytes per second download (that is: 100.000 kilobytes per second, download)

100 megabytes per second upload (that is: 100.000 kilobytes per second, upload)

It is not megabits, it is megaBYTES. Fiber optic.

But it is limited to 11 mb/s when I download with JDownloader and it never goes faster? Why?

What download are you testing? does the speed graph show a red line?
Have you tested same file in browser? What speed do you get at speed.hetzner.de ?
Is JDownloader on the same computer? or another one/nas device?
checked connection? 11 mbyte/s sounds like 100Mbit/s. maybe lan cable?

The speed graphics don't show a red line.
I am not testing a single file, I am downloading multiple files from multiple high speed mirrors, like: megaupload, wetransfer, etc. These mirrors are high speed, even in free mode. Despite this, I never go faster than 11 mb/s. Seems to be that JDownloader reorganize the speed among the downloaded files in such a way, that I never can go faster than 11 mb/s.

speed.hetzner.de does not show a gauge with the speed... you just download files. I tried to download the 100MB.bin. It was downloaded so fast, that I did not see any speed indicator in my screen, it took 1 second or less.

JDownloader is in the same computer.

I tested my connection today and yes, I got:

100 megabytes per second download (that is: 100.000 kilobytes per second, download)

100 megabytes per second upload (that is: 100.000 kilobytes per second, upload)

I did a second test.

At speed.hetzner.de, I tried to download the 1GB bin using JDownloader.

Now I had enough time to take some screenshots, I am sharing the screenshots here, please, take a look to them.



This file of 1 GB took 1 minute 31 seconds to be downloaded with JDownloader and the speed showed 11,30 MB/s

11 MB/s is 100 megabytes per second?

I am trying to show a screenshot, but this forum does not allow me to show the screenshot? Please, let me know how may I upload the screenshot

@mrmister: Please share a screenshot of the speed tests you made? in browser, so I can see speed there.
Also please share a screenshot of the about dialog of JDownloader?
Are you downloading to local disk or some network/usb share?
We can also take a look at this together via Teamviewer, just contact us via support@jdownloader.org

I'm talking about those speed tests that give you 100mbyte/s speed. I guess you do those via browser? Also please a screenshot of the about dialog, see https://support.jdownloader.org/Know...tion-directory for what dialog I'm talking about.

Hi, sorry, I don't understand your reply. What dialog do you want to see? The installation path? I am download the files via JDownloader and what I get is 11 MB/s.
Speed tests are done via web browser in this website:
**External links are only visible to Support Staff****External links are only visible to Support Staff**

In the page you said, there are several windows (dialogs) and I don't know exactly which one do you want to see?

@mrmister: a screenshot of a download in browser or your speed test showing a max speed of 100 mbyte/s
and from your about dialog of JDownloader, I want to know the used java version of your JDownloader installation, it is shown in the aboug dialog, see https://support.jdownloader.org/Know...tion-directory what dialog I'm talking about.

I can also offer you live help via Teamviewer, just contact us via support@jdownloader.org

Hi, sorry for my delayed reply, I was away.
Here are the screenshots you requested.

1) Speed test in web browser


2) JDownloader about dialog


When I download, the maximum speed I reach is 11 mb/s

Due my connection is broadband 100000 kbps (100 mb), I should get 100 mb/s and not 11 mb/s

Why do I get only 11 mb/s and not 100 mb/s

Bit vs. Byte and Kilo vs. Mega

11 MB/s is ok.

I am confused... I think I do not understand well the differences, perhaps, between bit, byte, etc.

11 mb/s = 110 megabytes per second?

@mrmister: speeds are normally states as bit/s unit.
your screenshot shows 99.576 kpbs (kbit/s) = around 100.000 kbit/s = 100mbit/s
1 byte = 8 bit -> 100mbit/s ~ max 12,5 mbyte/s -> 11 mbyte/s are perfect speed for your connection.

keep in mind that their are overheads in the tcp/ip stack, this is why you never get full 12.5
