Not sure what Jdownloader 3 is.. However

That behavior could be normal. It goes at max (4mb/s) until the end of the 200MB file, then has to handshake, and start over again.

Install a Bandwidth meter on your PC, and download some files in your browser, I can almost guarantee it is doing the same thing with the browser. Firefox and IE average the throughput, and don't display it realtime.

It depends on the host. RS for instance shows this type of behaviour for freeloaders. It sends data, then it pauses, it sends data, it pauses, etc.

No, that is not the solution.
That type of behavior is only happening with RS and jD combination. Other file hosters work fine with jD, and other downloader programs and browsers work fine with RS.

Please help.

Please re-read remi's message.

RS servers provide data in small amounts for free users. They do this by providing some data, waiting a while, and repeating.

JD reports what is actually happening. Most other programs hide this by averaging over a long period of time and report inaccurate information.

Real speed is MUCH bigger with other download programs, and also download time is MUCH shorter with other download programs, when downloading from RapidShare.
As I said, "... ...and other downloader programs and browsers work fine with RapidShare."

Free download from only rapidshare does not show constant downloads when you look at an accurate speedometer, such as that in JD.

The file size is only adjusted when the buffer is full or the file is completed. The buffer is at least 0.5MiB. Processing download packets has priority over saving to disk, which has priority over display updates, so you might only see changes between download bursts. When you never see updates during download, it could be a symptom that your computer is overloaded (a possible fix is increasing the priority of the java or javaw task).

JDownloader is at least as fast as other downloaders. However, if your system lacks sufficient resources, then JDownloader will not be able to work as quickly.

The most common problem (in Windows) that causes slow download in JDownloader is over-eager security software. Using Java or most security software with Windows version 6.x (Vista or "7") requires installation of a patch from Microsoft that they have not put into Automatic Updates or SP1.
Please see General Discussion -> Self Help Index for both of these problems.
_______________________

Because of the increased capabilities, JDownloader takes more computing time and RAM than most other downloaders. The next release will be greatly improved in both computing time and RAM use. Future planned changes will greatly decrease RAM use and computing time.

If you are using Windows, the "Commit Charge" should not greatly exceed "Physical Memory". The average CPU time while programs are running should not exceed 90%, or the OS may not be able to complete all tasks.

Default Viewed with a better speedometer

As you can see in the picture JD is only downloading in the low parts of the JD graph. This behavior only occurs with the RS plugin, so I doubt it is a problem with my machine.

Even if it is typical behavior, then still the graph is wrong. There is no traffic during the constant high parts. The plugin may be waiting for RS while it keeps reporting the same old invalid value.

I know something like this was common for RS, but not with wait periods of 10s of seconds. If there is no error (besides the graph issue) than the guys from RS really have degraded their free service lately. We now also have to wait 4 times longer before the download starts.

@drbits

It's not problem with computer or resources, it happens on ANY computer and with ANY firewall/AV.

jD from RS, 100MB file, looong time to finish.
ANY download method from RS, 100MB file, under 5mins to finish.

EDIT: @4Mbps connection.

Default Solution?

For me this problem disappeared this afternoon. Now I'm able to download at full speed without any pauses. I don't know if it is related but the only difference with this morning is that I installed the patch found here:

Default No, not solved

The problem is back. Weird enough it is again a Friday. I guess it is done by RS. It is commonly known that Friday is the day to download stuff.

(but then still the JD graph is wrong)

Then I recommend not to look at the speed graph on Fridays. I think this should be a small effort.

Note that I never use it.
