Same problem here on a Linux system.
Downloading 1 pacakage (23 parts) (non-premium) from megaupload. 2-3 seconds after the downloading starts, the CPU usage reaches 100%. $ java -version java version "1.6.0_13" Java(TM) SE Runtime Environment (build 1.6.0_13-b03) Java HotSpot(TM) Client VM (build 11.3-b02, mixed mode, sharing) |

for me it dose not use 100% CPU but i have noticed that javaw.exe uses 7-8% of my quad core, and then 70K memory, which seems high and i have all graphic settings on low.

New version of JDownloader has coding problems.
Particularly with older hardware it tends to be a resource hog & there is a conflict when other java based apps are running at the same time. Very buggy and unstable, some much better choices around |

Please, if you're an expert, indicate them in the source code. I'm sure the devs will appreciate your contribution.

HI all,
I got a similar problem. By CPU usage was going through the roof with my Ubuntu 9.04. After taking a closer look i realized there wasn't a problem with Jdownloader, but a System problem. I got to much IO/WAIT time. :( Ubuntu was having problems communicating with the hard drive. To test for this, simply try to copy a file that is larger then 1GB , and check under "top" or whatever how you're CPU is doing. By the way, now the problem is gone. Not sure why, probably because of some update |

It definitely has something todo with the download itself.
When e.g. waiting for the reconnect, CPU load drops to 5-10%. Immediately after the transfer begins, load rises up to 100% and above (2 cores). Perhaps some GUI refreshes in the download code or similar? |

Same problem here, CPU load is at 100% while, and only while downloading.
Minimizing the JD window to tray icon has no effect. I dont know if this helps, but when i look at javaw.exe in Process Explorer, i get this thread, which causes the CPU load: msvcr71.dll!endthreadex+0x31 |

we could find a possible source for the cpu problem, but we are still investigating the issue

the soft is now unusuable on eeepc, just freezes the system all the time.
waste of time, rubbish, time to find an alternate |

oprofile of jdownloader
The issue seems to be related with the high amount of times the java program reads from a high performance timer.
I've not seen the code, but may it be that the user interface is refreshed after a fixed amount of bytes are downloaded? The problem seems to be related to the download speed. CPU: Core Solo / Duo, speed 1000 MHz (estimated) Counted CPU_CLK_UNHALTED events (Unhalted clock cycles) with a unit mask of 0x00 (Unhalted core cycles) count 100000 vma samples % image name app name symbol name c011fe80 67945 57.4549 vmlinux-2.6.28-13-generic vmlinux-2.6.28-13-generic read_hpet <- here c011fe80 153 0.2252 c011fe88 21 0.0309 c011fe8f 67771 99.7439 00000000 16924 14.3111 anon (tgid:20717 range:0xb41e3000-0xb4683000) java (no symbols) 00009440 1 0.0059 000094b1 1 0.0059 000094ca 1 0.0059 00009c6a 1 0.0059 |

Found another thing... when setting the download speed to 10kb/s (pause), the load drops to 10-11% on the java process. So it has definitely something to do with the download-dowhatever-code.
