Status: RESOLVED WORKSFORME

(Toolkit :: Downloads API, defect)

Description

[Jon]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9b2) Gecko/2007121120 Firefox/3.0b2
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9b2) Gecko/2007121120 Firefox/3.0b2

Trying to download web pages for reference on another PC, but firefox 3b2 keeps hanging and occasionally crashes. Eventually, the page will download, so it's not all bad. IE works fine, which is odd for a microsoft product. :P

Problem with the .asp nature, or the fact there's lots of images on the page?

Reproducible: Always

Steps to Reproduce:
1.Download a webpage from the site I linked

Actual Results:  
Hangs the program.

Expected Results:  
Downloaded the file with haste, the page is already cached into the temp folder.

AdBlock Plus is the only plugin running, removing it makes no difference.

saving normal files is working (if you click for example on a ZIP link) ?

Yeah that works fine.

Note that bug 410131 (available in the nightly build from today) speeded up saving these files. I was testing this bug a few hours ago (with yesterdays build), and I can confirm that saving "complete" wegpages is indeed very slow. And blocking the UI. But now that I retest with today's version, the problem has disappeared !

I noticed that most files and images on these pages are very small, smaller than the 32K buffer size that was introduced by bug 410131. So maybe, they're now written in a single write-call ? They used to be written with multiple ones, probably every 1.5K or so (I didn't measure).

I see that it's pretty slow, especially the first time saving using "Web Page, Complete"; are you using that or "Web Page, HTML Only"?

It's not bad on the Mac trunk (10.4), for some reason; I see they're using http://web-sniffer.net/?url=http%3A%2F%2Fwww.3dtotal.com%2Fffa%2Ftutorials%2Fmax%2Fjoanofarc%2Fjoanmenu.asp&submit=Submit&http=1.1&gzip=yes&type=GET&uak=0.  They're using HTTP 1.1, so pipelining should be working...
