Build: 2001-01-21-03, Win2k The "file picking" dialogs for Save As and Open etc. are very slow when displaying the contents of a folder. For example, try to Open a file in a folder (or root drive) with lots of stuff in there... you can actually see the files being "painted" in the dialog. This is not too bad on my Celeron400, but if I there is a CPU-intensive background task (such as rendering with POV-Ray), there is a VERY noticable slowdown, and worse is that you can't click "Open" or "Save" until it is done painting.
Probably INVALID? The Open/Save dialogs for Windows platforms are just the native versions, I think. If so, that means Mozilla has no control over how fast or slow they are.
They might be the native versions, but for some reason they are slower than in any other program open at the same time, for example the one's I am running right now, which are Word, Notepad and Photoshop. So maybe it's the way we are calling the dialog? Or maybe they are not really native but they just look that way?
The dialogs are really honest-to-god native ones on Windows.... Over to XP apps.

Sorry for the spam, but does anyone else see this, or is it just me? I mean, maybe people with faster computers don't really notice it, but try loading some CPU-intensive apps and compare the performance of the dialogs here and in other apps. :)
This was already correctly assigned. ->file handling. Bill, are we doing anything that could possible slow these dialogs down?

Nothing, directly. I have, on occasion, witnessed this phenomenon. Closing Mozilla and restarting it clears things up. It could be a Windows resource problem caused elsewhere that just appears in the file dialog. I certainly don't see it all the time, regardless of what activity is going on in the background. We need a way to reliably reproduce this effect before we can do too much with this one.

I can corroborate that the file open/save dialogs are slower with Mozilla than other applications. It's not a sometimes thing, either, it's always slower. I've experienced it on multiple machines, as well. Walking directories via the open/save takes several times longer on Mozilla than, say, Internet Explorer. Scrolling the window in a directory with many files is slow in the same way, where you can watch it paint individual files or folders. Each one takes a fraction of a second, but it adds up. Seems like a memory issue. Perhaps other applications pre-cache files before rendering?
Just looking for an update on this. Are the file dialogs fully native or not? The problem I have with this is that during high-CPU-usage situations, downloading a file is very tedious because you can barely navigate the filesystem. For an easy way of duplicating this, just start to encode an MP3 or something and then save a file. That is enough to produce a noticable delay on my 400MHz machine. If you need more challenge, start rendering something in POV-Ray and encoding an OGG at the same time. Just anything to really tax the CPU. During these conditions, the Mozilla save dialog will be pratically unusable, but any other app (Word, notepad, explorer) will still respond.
