That's because SoftPC had to emulate the entire IBM-PC architecture, including the x86 processor, FPU, video, etc. All our Linuxulator has to do is translate Linux system calls into the appropriate FreeBSD ones, a much simpler task. For most programs, you shouldn't see any speed loss running a program under emulation. -Dan Nelson dnelson@emsphone.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
