Improve Apple Services with AirPort Base Stations

You can make iChat file transfers, iDisk, and Back to My Mac work better by turning on a setting with Apple AirPort base stations released starting in 2003. Launch AirPort Utility, select your base station, click Manual Setup, choose the Internet view, and click the NAT tab. Check the Enable NAT Port Mapping Protocol (NAT-PMP) box, and click Update. NAT-PMP lets your Mac OS X computer give Apple information to connect back into a network that's otherwise unreachable from the rest of the Internet. This speeds updates and makes connections work better for services run by Apple.

 
 

Benchmarking SoftWindows

Send Article to a Friend

One of the problems that Apple has faced with the Power Macs is that SoftWindows doesn't always behave as you might expect a real PC-clone to behave. That's not surprising, given that SoftWindows does in software what a PC does in hardware. Insignia has used various tricks to improve performance, but if you don't take advantage of those in testing SoftWindows, it will seem slower than it actually is.

Paul Kerr, SoftWindows Product Marketing Manager at Insignia Solutions, provided these suggestions on the nets for not only maximizing SoftWindows performance in normal usage, but also for giving SoftWindows a fighting chance in a demo situation. The difference in performance between the worst settings and optimum settings in any specific situation can reportedly be more than 100 percent.

First, you must compare apples with the appropriately configured oranges, so to speak. If the real PC has a lot more memory available for Windows applications than SoftWindows does, performance will suffer. So, if you're comparing SoftWindows with a 4 MB PC:

  • Use a 16 MB Power Mac.

  • Set the Monitors control panel to 256 colors.

  • In the Memory control panel, turn Modern Memory manager on, Virtual Memory off, and reduce the disk cache to the minimum.

  • Set the memory partition for SoftWindows to 12,000K.

  • In SoftWindows, in PC Memory, set Expanded Memory (EMS) to zero, and set Extended Memory (XMS) to 3 MB or 4 MB (this will leave between 1 MB and 2 MB of RAM unused, but will improve performance significantly).

  • In Windows Desktop, set the size to 640 x 480, with 256 colors.

However, if you're comparing SoftWindows with a PC that has 8 MB or more memory available:

  • Use a Power Mac with 24 MB of RAM.

  • Set the Monitors control panel to 256 colors.

  • In the Memory control panel, turn Modern Memory manager on, Virtual Memory off, and reduce the disk cache to the minimum.

  • Set the memory partition for SoftWindows to 18,000K.

  • In SoftWindows, in PC Memory, set Expanded Memory (EMS) to zero, and set Extended Memory (XMS) to 10 MB (this will leave about 2 MB of RAM unused, but will improve performance significantly).

  • In Windows Desktop, set the size to 640 x 480, with 256 colors.

In addition, here are a few other tips that can significantly improve speed in SoftWindows:

  • If you use Microsoft Access, use the larger RAM test setup.

  • Use the HPV video in the Power Mac 7100 or 8100.

  • Add a cache card to a Power Mac 6100 or 7100 for a boost of about 20 percent.

  • Install a fast hard disk (such as a 1 GB drive) to significantly boost Windows performance in general, and database access in particular.
