I regularly delete Chrome's cache because I did somehow "discover" that behavior intuitively a long time ago.

That said, it's totally silly to criticize security measures for slowing down a bit page rendering / navigation.

I'm taking a 50% slower Internet today if, in exchange, it's 100% secure. I know it's not doable and won't happen any time soon.

But those willing to sacrifice security in the name of perfs should be shot to dead.
