Jdownloader Memory consumption

**anumalas** · 09-12-11 at 07:58 PM

Guys

With JDK 1.6 and up-to-date jdownloader is consuming too much ram and I/o resources while downloading 2 or more files around 1GIG its taking and i/o exceptionally reduces other applications performance.

Typically I use 10-15 connections on each download.

Just now I have checked it and 5.93 GIgs of free memory went down to 4.92 on my MBP after launching jdownloader with 2 downloads with 15 connections each.

Does anybody using jdownloader and having such kind of issues?

And its consuming full internet bandwidth if no limits were set not even little KB's to open websites in browser.

If anybody knows tweaks Help appreciated.

I've noticed this too on my laptop. It does seem to be from multi d/l's for me.

Its not a JDK issue on MAC coz I am facing the same problem with W7 too. I guess the way Jdownloader handles threads is not balanced well. In a multi-download action (which is nothing but a multi threading) all threads are waiting for I/O and living in memory killing it up since every thread( each connection on download --> 15 connections means 15 threads / per file) waiting to write to HDD. I have replaced my HDD with SDD but still same problem coz of in-efficient way of balancing threads.

JDownloader is notorious for this. I've tried adjusting lots of settings and different tweaks, but memory was consumed regardless. I don't really care as much anymore as I put 12Gb of RAM into my iMac.

IDM and JDownloader are not used for the same purpose.

What makes you say that?

JDownloader makes your computer a bacon frier, of course. That's the only use it has.

It's most likely a memory leak in JDownloader itself. You'll just have to take it up with the developer(s) of the program themselves if that is the case.

Try taking out a stick of RAM and then see how much RAM it uses when less is available.

Tested this in Ubuntu 11.10 too. No memory issues but Linux uses Java from Sun's repository.

Are you using JDK 6 32 bit or 64 bit on W7?
