Status: RESOLVED WORKSFORME

(Toolkit :: Downloads API, defect)

Description

[[:nickname] Firefox User]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; es-ES; rv:1.8.0.1) Gecko/20060124 Firefox/1.5.0.1
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; es-ES; rv:1.8.0.1) Gecko/20060124 Firefox/1.5.0.1

Always I start a download, my computer starts to "microfreeze", so it's very unconfortable (specially with large downloads...).

Reproducible: Always

Steps to Reproduce:
1. Go to the web http://www.epx.epita.fr/misc/isos/kororaa-xgl-demo-livecd-0.1.iso
2. See what happens.

Actual Results:  
Computer started to "microfreeze" until the download finished.

Expected Results:  
Behave normally, without freezing my computer.

On the system monitor (I use Ubuntu Breezy), it shows that firefox-bin is using the 30% of my CPU, getting sometimes 100%, and using a total of ~115MB of memory.
My CPU is an Athlon Thunderbird 1Ghz, FSB 266Mhz, with 512MB Kingston DDR RAM.
After finishing the download, the CPU use returns to 0%.

Can you reproduce after trying the standard diagnostic? (http://kb.mozillazine.org/Standard_diagnostic_(Firefox))

Yes, I tried the Standard diagnostic, and it stills goes "choppy". I have to say I don't have any extension, and I was using the default options (except I had a "new tab button" on the toolbar, and links opening new windows where configured to open new tabs).

I have an ADSL2+, wich speed rate is now (it changes during the day between 10.5Mbps and 13Mbps of download, the upload is more or less the same, between 840Kbps and 900Kbps):

Line Rate - Upstream (Kbps):  	888
Line Rate - Downstream (Kbps): 	11966

Have you tried deleting downloads.rdf from your profile folder?
I think this might be a dupe of, or related to bug #91232.

I've seen the same behaviour. It is linked to the downloads list (CRTL-J) having LOTS of entries. Cleaning up the list will eliminate the performance issues.

Reporter, do you still see this problem with the latest Firefox 2? If not, can you please close this bug as WORKSFORME. Thanks!
