I thought I'd run some benchmarks comparing Native Mac OS with MOL Mac OS.

The specifics

a 7300/200 with a 400 MHz G3 upgrade card
Mac OS 9.04
Speed Doubler 8.0 running

Native Mac

MacBench 5.0 (G3/300 = 1000)

Processor = 1214
Floating Point = 1250

Helios LanTest (over 10 BT to switched 100BT netatalk server)

Write 1068 KB/s
Read 969 KB/s


MOL 0.9.48-1

unique_mol_ethernet yes
VNC as display, no other process taking up much CPU (mol reads 99% CPU)
sound_sync_value = 150

MacBench 5.0

Processor = 776
Floating Point = 1139

Helios LanTest
Write 204.22 KB/s
Read 810.45 KB/s


So, as much as you take any benchmark seriously, mol is about 60% as fast as native,
except for floating point in which case it is close to native.

Outgoing ethernet is way slow however (about 20%). Something for the network gurus to
think about...
