Default CPU usage

Why is the cpu usage so high for this?

I'm only downloading one file and its using 10-15% cpu 100% of the time.

dual core 2.66ghz

is there some settings i can turn off? Because it hasn't always been this high, used to only use a few %

I'm posting here because I'm seeing something similar since the last month, maybe two. Jdownloader started getting reeeeeeealy slow when I copy some links, not all it seems, and the linkgraber starts running, it goes to use 27% of the CPU.

Here are the logs for today. 18.04.14 08.15.24to18.04.14 08.14.13 jdlog://6847563166931/

Well i don't think its big (I think its currently small, i used to have like 20+ packages and thousands of links but there was no large cpu usage back then either)

What would be big for you?

In my situation, that in a very short period of time are removed the old archives and is also associated with the power CPU and HDD.

I think this problem was already presented ... I think happened to djmakinera, who handled thousands of links and then hung ... JD2 happened with few links consuming cpu and consumed many little ...

Number of links does not matter!

Well i dont have that many links so that can't be the problem

Anyways, after this latest update i'm noticing the cpu usage even when i'm not even downloading anything.

and its even higher, now its 15-20%

Yes this is normal at the moment. This is because if the window is not visible, then the table (list) does not need to be drawn. Drawing the table (items, progress bars..) needs the cpu. I'm sure we can reduce cpu usage even more, it just needs time
Log.Debug Mode: default: DISABLED (Domyslnie wyłaczone mam) Nic nie włanczałem...

editestowy - Moja aplikacja wydaje się robić bardzo cięzka lub GUI, przyciski (blokowac się) - jeśli zwiększe symulacje i w ustawieniach ustawie "natychmiast usuwaj linki pobrane". Oczywiscie nie odrazu ale jak zaczynam pobierac to robi sie stopniowo ciężka (bo zasoby rosną)
Linków mam teraz mniej o wiele mniej ale niektóre pliki tak szybko pobierac i tak szybko usuwac stare archiwa z logami, ze to obciąża albo dysk albo całą aplikację GUI. Prawdopodobnie duży odczyt $MFT czyli związane z dojściami...?
Najczęściej jest z "małymi pliczkami" bo wtedy szybciej usuwa i szybciej pobiera...
Jak dla mnie dla 1 symulacji - to za dużo CPU bierze...
Dla porównania "odpalę" jakąś wcześniejszą wersję JD2 z 2013 i na pewno aż tak bardzo nie obciąza ja nowy RDZEŃ.
Jeśli to wszystko pozmniejszam to czy "nie oparzę się na zaawansowanych ustawieniach", że coś nie zarejestruje lub nie przeanalizuje wszystkich linków?? lub napisz tak jak wiesz najlepiej sam...

Tyler - I do not know. I just clean up here. Ask Jiaz.
support@jdownloader.org

Edit:
editestowy - zmniejszyłem to dla testów ale nadal wysokie CPU (1 pobieranie).. nie mam innego pomysłu co jest nie tak...
Dojścia 800+/-
Wątki 47+/-

I think this is because you have debug and logging enabled and when you parse/download many links this may use a lot of CPU/Memory resources.
Try to disable debug (Advanced Settings: Log.Debug Mode), decrease the number of opened log files (Log: Max Log Files)/decrease max size of log (Log: Max Log File Size) and report the results.

And why is this only happening recently.... this never happened before (it was barely a few % during use)

15-20% cpu usage for downloading a file is ridiculous.

also dependant on what type of protocol your download is on, https chews much more than http. I've noticed large cpu loads under a single https download, more chunks you have worse it gets. This is due to handling encryption.

no worries, just thought I'd inform on the odd chance.

okay, well what other feedback do you need?

bump.....

What other feedback is required?

10-15% is a high cpu usage

and i went back and tried out jd1 again and it was barely using anything at all (like 1-2% max)

It shouldn't be using 10-20% cpu just by being opened.

I get an high cpu ussage when I grab links on a site or when I download with premium accounts. When I don't download with premium acounts and don't grab links its 10-15%.
