Leopard performance on G4 Powerbooks (early reports: excellent)

Multimedia said:
What did you have to do to make that happen? Is it in preferences somewhere or did you have to do an esoteric hack?

If a hack please explain or link to the explanation please.

It was already mentioned that the leopard install automatically adjusted to the specs of the host, and for some reason turned off menubar transperency.

As I have written earlier in this thread I haven't changed or hacked anything. Probably Leopard adopts automatically to lower spec'ed machines.

As I have also written earlier, performance is already excellent with 768 MB. That is for browsing, iPhoto, and iTunes. For Photoshop et al more is probably better.

Awesome. It sounds like Apple is really taking care that the new eye candy doesn't bog down these G4's!
 
I've just compared the dock reflections to a 2,4 Ghz glossy iMac. No degradation for the lower specs here, they're identical. The iMac also doesn't do real 3D rendering on the dock, but inverse scrolling as the Powerbook (see my earlier post).

He wants numbers, benchmarks. Isn't that equally obvious?

I'm sure those MacBench scores will start pouring out soon.

I'm not sure wether benchmarks will even show significant differences. The fast UI speed could be solely explainable by efforts to hold all relevant UI data in memory at all times. Better GPU utilization of the general UI elements may also be a factor.

All this may not be appropriately reflected by common benchmarks.

Calm down champ. First, don't be rude. Second, I'm merely saying that I'm waiting for more reports because while I'm very excited at the news so far I know it's not the be all and end all of user experience just yet. It won't hurt for me to evaluate after more users pick up their copies. It's just the way I handle all my decisions and I would respect you if you respected that instead of making me out to be the person who says 1+1=3. Good luck with your installation of leopard Multimedia. I'll definitely hope you post your experience with it to help anyone feeling reluctant to upgrade.

You sir, are a gentleman.

Multimedia, we all know previous upgrades to OS X improved performance on older machines. That's no *guarantee* that it will happen again, and for all machines.

I considered that before posting.

However, if Leopard provides a speed-up for all apps, particularly those that make extensive calls to system libraries, this should be reflected in benchmarks that mimic real-world applications.

Alternatively, one can time their own oft-used apps in Tiger and Leopard, keeping all hardware factors unchanged, and note the difference.
 
12in Powerbook
1.33GHz
Maxed out RAM
Combo Drive

been using it for the past 3 days and i have to say i am impressed. aside from certain things im not "feeling" (ill just have to get used to) i say the performance is very impressive. its not sluggish at all, even after installing the following.

iWork '08
iLife '08 (iWeb & iPhoto Only)
VLC
Peer Guardian
Tranmission

not alot of apps but still. there is a minor lag (fast scrolling before page loads) but not something thats too concerning, safari is very fast i must say and the loading time also. without restarting for the last 3 days everything seems all well esp when i needed to restart tiger more so than i do now. ive been quite busy the last few days so i havent gotten to tinker with everything but i have to give apple a thumbs up, esp after the whole vista hype disappointment at work.

- When you unplug your Time Machine external, nothing happens, but the instant you plug it back in, Time Machine does a backup -- in the background. You never see anything, but it silently backs stuff up every time that drive is connected.
- Feels fast on a PowerBook G4 1.33GHz

Here's another endorsement. My copy just arrived at home, can't install until later tonight. I'm sure eager to see how it will fare on my PB 12".
 
Woohoo! Everything is up and running now (Erase and Install). The hardest part was getting my printer working via the Airport Express...

I've been very impressed with Safari -- the pages are loading very fast on my wireless. My Office 2004 documents are opening very quickly. So far I'm very happy with this, also keep in mind I was using Panther before on this machine.
 
I am pleased to report that after indexing was completed, all three of my G4 systems on which I installed Leopard last night (PB 1.67, dual 867 MDD, dual 1300 Sawtooth) are performing excellently. I think the response time for the finder and most apps has improved, in the least, it has not gotten any slower. Interestingly, prior to the upgrade, my modded Sawtooth was crashing and getting kernel panics constantly, none so far in the last 24 hr.
