I don't know about 25%, but if you start it from Terminal like this:
nice /Applications/Mail.app/Contents/MacOS/Mail &

it will be given a lower CPU priority than other programs.

Why is that, what does that command tell the Terminal to do ?
 
This has been a great article series at AI. Part history, part humor and the expense of Windows, and a detailed look at what's new in Leopard.

I think I'll start with just TWO spaces before I get all crazy!
 
Mail on the other hand, now there's a CORE HOG if I ever saw one - I would love to limit Mail to 25% of a core if I could.!

Weird. I run Mail 24/7 and except at the moment it's receiving mail, I seldom see it use more than 0% CPU. It goes up to about 6% of a core when checking mail from 4 accounts at once. (And uses less than 50 MB of real memory.) This is on a Core 2 Duo iMac.
 
Lots of people on these forums seem to be having dreams about Leopard.

Snoooorrr... , I'll put the porn in this Space; the penguins in this Space; I'm being chased by Zombies but I'm stuck in mud in this Space; but in THIS Space, I'm a viking!... Zzzzzzz
 
Does anyone else have the problem when trying to view the video that was linked in the article or linked on apples page it always crashes the browser? I've tried it from the most recent FireFox and most recent IE7. I have to use a PC here at work, I don't know why it would crash the browser though....
 
I wonder

how this will influence my use of exposee , i would not be suprised at all if i would stop using it and use spaces instead, time ( hopefully within 3 weeks ) will tell .
 
How about a "one core per desktop" mode, allowing easy user CPU allocation?

Not such a good idea. You have four cores and four virtual monitors. You are looking at only one of the three screens and interacting with whatever is there but 3/4ths of your compute power is tied to inactive programs.

I have a better idea. Let the "compute power" follow the demand for same. Why not write a program. Call it a "scheduler" and place in inside the OS kernel and then whenever a core becomes free the program will choose which of the processes that are marked "ready" to run. The schedule can use a lot of information to decide.

If users want to influence the scheduler thay have means already. See the "nice" manpage
 
I know for sure "Spaces" will be popular. I use a Linux system daily here at work with a Gnome desktop and I keep six virtual desktops on the taskbar. I've used this feature for years, going back to the late 1980's Even backin the days before graphical screens mice and Windows. I used a feature like this on a plain ASCII terminal where function keys would give you another virtual terminal. The idea has been around for as long as there have been "glass teletypes" Well maybe even longer there was a crude method even with the old paper teletype terminals. "Control z" would place the current session in the background and then you could toggle between the two session -- this was n the 1970's.

It's good that Apple has finally added this feature. But now that I have a 24" LCD screen I don't need it so much
 
I've had Apple dreams but none about Leopard yet.

Never been much a fan of them multiple desktop features. But if Apple can do it well then I might just switch my old fashioned ways.
 
Very nice! I first used work spaces waaaay back in my HP-UX days almost ten years ago. (damn, I feel old)

HP-UX's Visual User Environment defaulted to six workspaces but the number was configuable.

Nice work, Apple!

I switched to Mac OS X from Windows because it had a lot of stuff that my Amiga had back in 1985. If I remember correctly you could move thru screens with Amiga-M and Amiga-N. Also you could move your mouse to the top of a screen and slide it down.

It's nice to see another old friend (feature) added. :)
 
I don't think so...

I really like these Apple Insider features, but for heck's sake, I WANT A RELEASE DATE, so I can go out and buy my MBP and get a copy of Leopard via up to date....

BTW- Are they technically allowed to do these without violating their NDA, or is apple turning a blind eye, because it's free, very positive, advertising?

Basically I don't think that AI is under any NDA. I doubt the admins have an ADC account. They are collecting informations from their users.

And btw they are just touting all those features, that Steve demonstrated during his WWDC speech. I remember Finder, stacks and stuff to be in Steve's speeches. The only thing they spoke of, that Steve didn't mention anywhere IIRC, was the feature about Preview.app.
 
I must be the only person here who doesn't care about this.

Right now I command-tab to the program I need and use it. Repeat as often as needed.

That's it. Everything I've read about Spaces makes it seem like more complication without any added benefit. That's not anything to be excited about in my book. I doubt I'll ever use it, but I'm glad you're all excited! :)
 
How Can You Use Activity Monitor To Lower Core Usage On A Particular Application??

One can use the Activity Monitor to prioritize apps.
How? I have Activity Monitor open all the time and I don't see how I can minimize Mail's core hogging behavior or any other app's for that matter.

GAWD.Nevermind.I had a Windows flashback. sorry :eek:
No prob. ;)
 
What do you think will happen with Spaces if I already have an external screen hooked up to my iMac? Will you be able to leave that one alone while switching the other screen? And with the external screen have the option to have multiple spaces as well?
