IFF the swapping is what's causing the slowness, yes. But you were
saying that Opera is also using a lot of CPU, so the speed issues you
have may not just be RAM-related.

Depending on what you have in those windows, running the Opera
equivalent of "NoScript" and only allowing scripts to run on pages that
really need them might make a dent in the CPU usage. Many sites have
badly written JavaScript elements. And a lot of JavaScript is for purely
aesthetic or advertising purposes. Might be worth trying.

I run with NoScript blocking everything by default, and generally only
need to turn on scripts on sites that use things like gallery software
or shops. Add in Ghostery, AdBlock and PrivacyBadger and it's amazing
how much crap I don't see any more :-) Liam says AdBlock itself chews
RAM though - haven't seen that myself, but I don't use browsers nearly
as much as you and he do.

Have you tried opening a couple of hundred *empty* tabs to see if Opera
still chews RAM/CPU?

Regards, K.
