Ah but I don't have any doubt regarding Linux performance, problem is 
that I'm building under Windows where performances are an order of 
magnitude lower. And because I have to split my generated files so that 
FPC does not hit the 2GB memory limit (which it does for a 15M source 
file), the disk performances are getting more critical.

Thanks for the testing anyway.
