Compiling on your LC475 means a lot of I/O. You have the benefit of pseudo
DMA to your SSD because the mac_esp driver supports the PDMA hardware.
OTOH, the IIfx has SCSI DMA hardware that should out-perform the LC475
(I'm sure MacOS benchmarks would confirm this). Unfortunately, the
mac_scsi 5380 driver can't exploit the IIfx DMA hardware, so I/O
performance on the IIfx is rubbish compared to the LC475.
