Does anyone know if you can get Remote Desktop Connection to work with XP Home? VNC never works right. At least to control the PC from the Mac, I can control the Mac from the PC.
Level 3 (L3) Cache: When processor speeds are relatively close, the presence of the L3 cache will usually have the biggest effect on performance. VPC often translates a block of x86 code which is then called repeatedly. An L3 cache can often hold an entire block, which avoids the slow loading of the block from main RAM accross the system bus.
looks like the comment about bus speed was right on. l3 cache shouldn't matter so much now. NM.
...but it'll be significantly slower on the G5 than it was on the G4.
SO.. VPC uses the G4-specifik isntruction known as pseudo little-endian mode with doesn't exist in the G5. Since the G5 can do either little- or bid-endian, isn't there a similar instruction do PLEM in the G5? VPC will have to be rewritten to some extent, but is it certain that the G5 "optimized" version will be at all slower in the end? Might there be somthing in G5 that will make VPC even faster? The G5 _is_ built for running Linux after all, an OS that is optimized for litte-endian operation. There must certainly be some Linux-applications that would benefit greatly if there indeed was some sort of on the fly conversion of little- to big-endian (and vice versa?) built into the G5.
...but it'll be significantly slower on the G5 than it was on the G4.
I currently plan on purchasing VPC within a year but I was holding off until the next version since I don't require its services immediately. However, if M$ reworks VPC to run without PLEM support (albeit significantly slower, especially on G4s) and I don't plan to buy a G5 in the near future, should I buy now while I can still get a "workable" version?
The part that really befuddles me is *assuming* Apple knew the G5 would not run VPC, why would Apple be testing Panther for compatibility with VPC which is 1 of 6 apps they are testing for? I know of course, everyone without a G5 will still run VPC, but why not just assume it will run? It seems to include VPC in their list of apps to test for, they place a high regard for VPC. The other apps, are DW, Photoshop, iSync, iCal, iPhoto and somethingelse. So if it's in Apple's 'core' of apps to test their OS for, it seems they would make sure that their new tech G5 would run it. Maybe they knew about it and just hoped Connectix would update it, but they had to realize it would be a big deal for a lot of potential buyers that need to run VPC. I still can't believe it will take M$ 'well into 2004' to update VPC.
Something just sounds funny to me. The whole core testing of the apps with Panther yet knowingly disabling VPC from running on your holy grail desktop? Weird.

What does Panther have to do with it? You could be running Jaguar, Panther, or Garfield for that matter... VPC wouldn't run on your G5.
When you talk about VPC being "knowingly disabl[ed]", it sounds like you might be imagining that the only thing stopping VPC from running is an arbitrary test for the G5 that stops VPC for no good reason.
VPC is disabled for the G5 in the sense that a collapsed bridge with a barricade is disabled for your car. Sure, you could take out the barricade, but you're still not going to have much luck crossing the river.
Can someone please post the steps required to make VNC work? I'd love to control my PC from my Mac. I'm new to this, and would appreciate anyone who could offer some instructions.

No problem! This is from memory, so apologies in advance if I forget something.
First, on the PC you want to install the VNC server. I strongly recommend using the RealVNC build, available at:
I haven't tried the beta of version 4.0, so I can't say if it'll work. Again, I gotta recommend the version referred to in the above link.
Unzip the file you just downloaded on the PC, and run the installer. After installation is complete, you'll be able to set the server properties. Make sure that "Accept Socket Connections" is checked, enter a password, and click "ok" (the other defaults should work fine for you).
You can then install the VNC Server as a system service; I like to do this, that way when Windows crashes on you (and crash it will! ), when you reboot, the VNC Server will be running without you having to take any action.
If you don't know the IP address of your PC, run the command prompt and type "IPConfig". Write this IP address down.
Now, the Mac side.
My favorite VNC client for OS X is Robert Kedoin's VNC Viewer, available at:
Download the binary version, unStuff it, and copy the VNCViewer icon into your applications folder.
Run the VNC viewer. Select "Open" from the "Display" menu, and you can enter your PC's IP address. At this point, VNC should prompt you for a password; enter the password you created on the PC VNC Server, and you should now see a virtual image of your PC on your Mac.
Again, I apologize if I've forgotten anything, this is from memory.
...if M$ reworks VPC to run without PLEM support (albeit significantly slower, especially on G4s) and I don't plan to buy a G5 in the near future, should I buy now while I can still get a "workable" version?
....no need to use VNC. Just use Microsofts free Remote Desktop Connection software. I use it to use and administer my PC at work.
Or if you want a non-crappy "Bad Carbon Port*" application which doesn't mess around with your PC and crash on your Mac all the time, try rdesktop (available through Fink).

I very VERY much doubt MS will "get rid" of PLEM. It's like applications which are "AltiVec-enchanced" - they check what processor you are running and then choose to run AltiVec or alternative code.
The most likely (98%) senario is MS still supporting PLEM, and implementing alternative code for the G5.

The G5 bus also has a huge latency compared to the G4 L3 cache.
Go to arstechnica.com, for example, and read about that.

Sorry, where was this quoted?
My WAF on getting a G5 was based on VPC running faster, now I find out it won't even run (untill well into 2004?)
