Is it really >> that much faster to justify dedicating RAM to it? Or, asking the question in a different fashion: "will my machine run *that* much faster by being able to use that (small) portion of my RAM which is /not/ dedicated to browsing?" From an OpSec POV, I also consider having to 'download it again' a good thing. My browser doesn't store anything between sessions (yes, sessions, not reboots). > No. But we were talking about putting web cache in RAM as a strategy > for minimizing writes to physical disk, not as a way of speeding up > web browsing. It also prevents writing data to disk that you don't want persisted or recovered at a later time. (Think TAILS, Tor or whatever other OpSec reason you may have) If it's been on your disk, it can be (fairly easily) recovered.
