Having recently discovered how to disable swapping, I now know it's
the OS' fault. While preliminary reports* suggest Snow Cat is much
improved, previous versions OS X are way too swap-happy. (I can't
test Snow myself on my G4. Damn!)


With swap off on my PB G4, I'm finally seeing an appropriate
performance boost from doubling RAM, which had been a huge
disappointment. I never could figure out why opening a few dozen web
pages of less than 100 K each required gigs of swap files. Now I know
they don't and dynamic pager (the swap binary) is a buggaboo Apple
ignored for a decade.

My CPU and disk used to be churning away constantly, now with
swapping dead it's like escaping hell into nirvana: peace, quiet, and
much much more responsive/capable machine (e.g, more apps/windows
open at a time).

BTW, I'm working on posting details how to kill swapping easily;
maybe OSXHints will post one-step hack I stumbled on. (I've not tried
above method as I don't know how to compile.)

Also, there seemed a significant improvement in iCab devouring
RAM/swap some months back. But it may have been an OS update, as
developer said he didn't know anything he'd done to improve things.
And there was a HUGE improvement when iCab incorporated WebKit last

Further: any page with Flash content is a real drain on iCab,
consuming big % of CPU until one closes it, regardless whether it's
in focus or not, or whether the Flash file is downloaded! Ah, Adobe!

It's got enuf features and almost always comes through on pages iCab
can't, so it's my second choice.

Years since I looked at Opera, sounds worth another try, as Safari is
way too minimalist/klunky and Firefox so bloaty.

Delighted to hear others use iCab. I'm not alone!
