I use a lot of tabs and after a while less recently opened tabs take some time to become responsive, which I guess is because they're being un-cached to HDD as they're not required.

So after creating a Ram-Disk I have two options, use

--disk-cache-dir="G:/"

switch to do what it does. Or what I'm currently doing: using a directory junction for

"[...]\AppData\Local\Google\Chrome\User Data\Default"

to move that entire folder over to Ram-Disk. I thought this would be better than just disk-cache but what do I know. Is it?

As one can guess it'll be a pain saving/loading the Ram-Disk image each time I start chrome but if it really is better than the former approach I'll write a script or something.
