This old machine can load pages faster than my newer PowerBook running OS X 10.1.4 on 192 megs of RAM (Yeah, I know my RAM is still too low to get the most out of OS X…). But with OS X’s true multitasking capabilities and my work style – I flip between applications and tasks frequently – the slower browsing speed is not a deal breaker.
Gee, that’s funny, on all of the machines I use– from G3 iMacs through to my powerbook G4, I don’t suffer from this problem. I use LaunchBar to switch between apps and, as such, my hands area already on the keyboard and ready to go and the delay between app switching takes about the same time it takes for my brain to focus on the various windowsthat just popped forward.
First– get more memory. Memory is cheap, even with the recent price increased. 512MB is my minimum. Not because OS X, in itself, is a memory hog (though the graphics layer certainly is), but because the operating system will take advantage of every last byte of available memory to buffer access to the disk.
Virtual memory is great, but only hitting the disk once to bring in a hunk of data is far, far superior.
On a powerbook, this is especially crucial as portable hard drives are slow, Slow, SLOW! Any virtual memory activity on a powerbook is guaranteed to be noticeable simply because the drives are slow.
(I would suspect sticking a bunch of memory in your ‘book will also increase battery life by decreasing page swaps… but I haven’t remotely qualified this at all.)
I also try to avoid slow applications. I find that a lot of the carbonized applications out there are not very well engineered. The same can be said for Cocoa apps, but the very nature of Cocoa means that the core still plays well with the rest of the operating system.
Instead of IE, use OmniWeb 4.1b4. It is faster than IE by leaps and bounds. It doesn’t pause very often, either– something that drives me batty with IE.
Chimera– though very alpha– is blazingly fast, as well.
Obviously, it isn’t OS X that makes browsing slow. It is a combination of bad engineering or good engineering for a completely different system [OS 9] that has been ported, but not fully optimized, for OS X. iCab, Opera, and Mozilla all suffer from this– they are all nice browsers and each has their attractive strenghts, but they all feel like they have not been optimized properly.
I have also found that some applications– all Carbon so far– have a nasty habit of consuming a bunch of CPU when doing basically nothing. Microsoft Word will “idle” at 50% CPU utilization unless you turn off live word count, for example.
Certainly, there is a great need for optimization throughout OS X. Given the history of the operating system from the NeXT day, it very much appears that history is repeating itself. Every release of the NeXT operating system very much followed the ‘Make It Work, Make It Right, Make It Fast’ philosophy of software development.
It seems that some of the third party developers are stopping the Carbon parts in between Right and Fast. It works Right, but it isn’t Fast because the code still assumes an OS 9 – like operating environment.
