Why PearPC is SO slow?!
Posted: Sun Jan 08, 2017 6:28 pm
Hello!
I'd like to ask this simple question (maybe, it's been already asked here) - why the hell is PearPC so extremely slow on my very fast machine?! My host hardware CPU is Intel Core i7-2600 @ 3.40 GHZ (4 logical + 4 real cores). The PC has 8 Gb of memory, NVidia GeForce GTX 570 video adapter and new SSD with W10 64-bit on it. Initially I tried PearPC 0.5.0 from the distant 2011. The OS installation process was very slow even on generous settings of the emulator (G3 CPU, max amount of DRAM, 50 ms for redraw interval). Then I switched to newer 0.6pre and increased redraw interval to 100 ms. Nothing has changed practically. Well, it became slightly faster but still works 10-15 times slower than the host system.
Now some fun part - I've been installing Mac OS X Tiger 10.4.6 for ~13-14 hours! (took one night + one morning). Ok, when it got installed it's still slow: all file read/write operations are performed at 300-400 kB/sec, the internet speed is limited to this value also. Although video renders without any noticeable delays (and the mouse moves almost without delays), I have to wait for several seconds to several minutes to, say, open Finder, mount .dmg image, copy some file from one folder to another etc. In comparison to PearPC another emulators such as SheepShaver and Basilisk II work much faster - not so fast as the host but I'm almost satisfied with them.
Well, I'm gonna give it up, erase PearPC from my HDD and forget it as a bad dream. But finally I'd like to know if there's something to do with PearPC to speed it up or not.
