This is interesting. However, considering how 4GB to 8GB RAM is getting so common nowadays, using a ramdisk e.g. a tmpfs partition is quite useful. I've set Firefox and Google Chrome to use a 1 GB tmpfs partition for their cache and the performance improvement is clearly visible.

Why use a disk cache on a ramdisk instead of using the memory cache of the browsers? Is it to survive browser restarts?

Do they have the option to only use a large ram cache?

Is it possible to map RAM as VRAM? Is that called shared GPU memory? Can it be adjusted in WinNT/Linux? Some recent console game ports need/want 3+ GB VRAM. Upgrading VRAM is impossible, RAM is easy and cheap(er).

Yeah, it would be similar to shared GPU memory.

Earlier quoted context omitted.

Since just about the first version of Netscape (that I can remember), if you select cache in the settings dialog, there are two settings, one for how much disk space to use and one for how much memory to use.

(I had to double check just now since you asked. Yep, still there.)
