I read this post because, as you probably know, there was an interesting thread about the start times for BIAB on the PC. That's great news about your Mac version loading so quickly.

55 seconds seems way too high for your PC, though. If I recall correctly, some users had success lowering the times by excluding the /bb folder or at least BBW.EXE from their malware scanners. You might want to search for the thread and revisit any other tips there to see if you could improve things.

For other Mac users reading this thread, 55 seconds is not the norm for a PC. On my old Core II Duo, I get about six seconds. Admittedly, the main improvement occurred when I installed an SSD as my boot drive. Other users with better PCs than mine but regular hard drives report times more typically in the 7 - 12 second range, if I recall correctly, with the occasional cold start taking sometimes much longer but not consistently as long as yours.
