Systems, there is a checkbox titled Enable JIT Compiler (this is not available on PowerPC). In SheepShaverGUI, there is a JIT Compiler tab which is a definite answer to prayer. Is there any way to improve theįortunately, yes. Graphics tests alsoĭemonstrated a similar speed penalty, dropping from the G5's score of around 35ĭown to an embarrassing 3.2 on the Intel. Same test run on the much faster Dual 2.6 GHz Duo Core Xeon Mac Pro yielded onlyĦ.0 / 1100 for PPC and a lowly 0.6 / 15 on 68K. On a Dual 2.0 GHz Power Macintosh G5, SheepShaver scored 35 / 1700 for PPC and 3.2 / 115 for 68K. To average these differences out, we will use Speedometer's facility to average over 10 tests, and use only two Varying numbers, as it is highly dependent upon other background activity on Slash-separated pair of numbers to represent these, eg: 38.973 / 1516.224 for Importance for emulation tests, we will continue to use the convention of a Also, since the CPU and Math scores tend to be of highest Since Graphics and Disk performance areĮssentially the same across 68K and PowerPC, we will not distinguish between Speedometer also allows you to run these same tests under 68KĮmulation to see the 68K performance. Which we can measure these four areas: CPU, Graphics, Disk and Math, each value This month, weĬontinue by examining preference settings which can be used to dramatically Power Macintoshes, but involve true emulation on Intels. Understandable considering that SheepShaver's G4 emulator is a simple 'pass-through' on Performance levels on PowerPC-based Macs (under some circumstances, surpassingīut found it to be tremendously poor on Intel Macs. When we ended last month's examination of SheepShaver, we discovered that we obtained quite acceptable To improve performance in SheepShaver & Basilisk and consider otherĬlassic Macintosh emulators, including Mac-on-Mac, PearPC, Executor and SoftMac. This month, we continue by exploring ways Started examining performance of these emulators, concluding that Power Mac Our review detailed usability, robustness and installation details. The unusual Classic application which still supports 68K, SheepShaver remains the most important of the three we discussed. PowerPC-based Macintosh, whilst the other two emulate a 68K Mac. All three areįree and cross-platform, running on Mac OS X, Windows and even Linux. To running Classic applications on Mac OS X 10.5 Leopard: SheepShaver, Basilisk & Mini vMac. Last month we investigated three solutions
