I have an orchestral score with 181 bars and 18-20 staves per system, and it compiles in about 7-8 minutes on my laptop (about a year old with 3 GB RAM, dual-core processors, etc) but takes more than an hour on my old eMac (5 years old, 1 GB ram, 1.25Ghz G4 processor). The processing has always been slower on macs, in my observations. Even on my nice Intel iMac at work, which has pretty good specs, it always takes considerably longer than on my Linux laptop.
