VirtualPC 5 was the first OS X version which took nearly 6 months to release from beta yet performance was still rough, v4 had a beta test OS X version only given out if you bought v4 at MacWorld NY. On a random note for Panther/Tiger PowerBook owners, SoftWindows 5 & RealPC work under Classic which shocked me as VirtualPC can't. Though it will support USB 1 devices.ĭepending upon someones' needs if your software isn't heavy on MMX/SSE/FPU, even pre-OS X VirtualPC will be fast at the "rated" Pentium 90-166Mhz range on a 603e/604e/G3 era Macs. I am disappointed that Virtual PC still apparently lacks USB 2 and FireWire but, I guess that was too much to expect. Instead of getting a CPU that rates at about 557 MHz I now get one that rates at almost 700. However, running Virtual PC 7 under OS X 10.3.5 on a Dual 867 with a Radeon 9000 video card I found the speed improvements are very real. I found no real advantage to using Virtual PC 7 with Ramdisk Creator. Loren Olson reports good performance with VPC 7, but found no speed improvement using a RAM disk: This way you don't have to copy back the main Virtual PC disk image to your hard drive. This time, create another PC drive image located on your hard drive for the specific purpose of saving your data. Otherwise, your data will be deletedĪ third strategy is to copy the Virtual PC app and Virtual PC disk image (if small enough) to the RAM, as just describe. Just remember to copy back the PC disk to your hard drive before ejecting the RAM disk. If you are running Windows 95 or NT, then the Virtual PC disk size is around 200 MB. ![]() You can REALLY get a huge performance gain if your Virtual PC disk image is small enough to also copy to the RAM disk. If the Virtual PC application gets accidentally deleted from of RAM disk, just copy it back to the RAM disk. When you launch Virtual PC from the RAM disk (instead of the hard disk), there's noticeable performance gain.Īll of your changes are saved on the Virtual PC disk image located on your hard disk, so your date is safe. Create a RAM disk just big enough to contain the Virtual PC application, then copy VPC to the RAM disk. I have gained Virtual PC performance by using the RAM Disk Creator utility. He used a utility called RAM Disk Creator (US $15) to create the RAM disk in Mac OS X. IDK if anyone has seen this before( ) but it claims that Virtual PC 7 is faster when used with a RAM disk, here is an excerpt from the link:\Ī reader named Ed describes how he got performance gains in Virtual PC installing it on a RAM disk, a virtual drive volume located in RAM, rather than on the hard drive.
