Okay. Still trying to understand this.

Is the 'fsync' problem, the differences for you, with the same page? I ask because so many pages are so very active today. If it is a page, or several? If you would like I would try them from here.

It doesn't matter so much about the page. Any page will do. From my limited testing it did it on every page. It was like click bookmark, page loads, gets to end of loading, eight fsyncs within a second of each other. Click another bookmark, page loads, gets to end of loading, eight fsyncs.

The page, http://www.news.com.au/, that was in the beginning of this thread, is in IMO a pig of ads and Flash. And without the 'protection' of the two extensions that I mentioned it did bog down my Firefox for a second or two. Somewhat but not much. But nowhere near as the OP, and others, talked about in their posts.

I honestly do *not* see the halts that you, and others, nor the other things many are writing about here. And this was using Firefox 3.0bpre5.

I am puzzled. Unless it could be differences in Internet access or differences in hardware perhaps? Or a combination of differences in both?

You only see this end you do intensive i/o stuff. The easiest example, dd if=/dev/zero of=testfile bs=2M count=1024. Then start clicking through pages in Firefox. It will almost surely become unresponsive, and I don't mean just you can't click on anything. I mean you switch to another window and back, and it won't even redraw itself. You will now just have a big grey window where firefox used to be, till it comes back. Which sometimes it comes back within a few seconds, but sometimes it won't come back till the write of other program, like dd, is completely done. You can also see this with VMware Workstation while creating guest images, or doing heavy guest i/o, like say installing a bunch of updates in a Windows guest. You can see this with virt-manager and creating a new guest image. You can see this with kernel compiles.

Well now this, what you are describing, sounds more and more like hardware

limitations instead of some specific Firefox related problem.

I would think that any kind of intense disk activity or CPU usage would
cause programs to stutter as well as other things.

Perhaps your view of this situation is too narrow?

 Also the next e-mail in the thread hits on the same topic, use of sqlite.
