[Pearpc-users] Speed of PearPC

[Simon B. <sb...@op...>]

Thanks and congratulations to all the developers of PearPC. I take my hat 
off to you. I'm running Mac OS X version 10.3 on PearPC 0.4pre on Fedora 
Core 3, with the ethernet emulation working and internet access through a 
squid proxy. CPU is x86-jitc and video is through SDL. The host is an Athlon 
XP 1800+ with 512 MB RAM.

I don't need any fancy drag-and-drop when both host and client are running 
SSH and I can just type scp from either machine. SSH takes more than 10 
seconds to connect, but then transfers files at an acceptable 400 KB/sec.

Of the 6015 MB hard disk image, I have filled up about 4600 MB just by 
installing all of Mac OS X with X11 and the developer tools.

Compiling and running my own programs on PearPC (such as the raytracer I'm 
writing) seems to run around the same speed as my old 486 which runs Linux.

Raytracing a relatively small, simple image (200x200 pixels, no 
antialiasing) takes 1.4 seconds on the host PC, but takes 75.4 seconds on 
the emulated Mac. That's a ratio of 53:1, or an equivalent clock speed ratio 
of around 1530 MHz : 30 MHz.

I noticed that when running on the X11 video system, when the client shuts 
down, PearPC gets an Xlib async error and PearPC doesn't exit until I 
manually close the window. That problem doesn't occur with SDL, which is 
also better since it supports full screen video.
