Thank you for the reply. I don't think that I want to put the Cache on the RAM because it would wipe out all the site date each time. Sounds like a cool idea, but there's certain things I want to be saved. It is nice not to have to use a swap file though, although I'm wondering if I might actually need to upgrade to 16Gb of RAM for that these days.
Anyway I think that some of my addons may have been the trouble. As per one member's recommendation, I switched away from Adblock Plus and that seems to have sped things up some. I also got rid of the youtube dark theme addon when I remembered that youtube has one natively in the site.
As for sites that flash a bright white screen before loading the site in dark theme mode.. this site is one of them. Here's another site. Also note how long it takes to load this site:
Granted that isn't actually all that long, it's just longer than I'm used to waiting on that site. I use windows as a comparison (i know, for some strange reason that just makes linux fanboys scream while clawing their eyes out) and it does not flash the white screen first on either site, and it loads slower sites slightly faster. Who knows why. But again, it does seem to have at least sped up a bit since getting rid of those two addons.
