Hello, I have a simple, maybe obsolete, question. In kernel config templates (GENERIC) for FreeBSD 5.3/AMD64 I found some compatibility options, namely options COMPAT_LINUX32 options COMPAT_IA32 (options COMPAT_43) The system I wish to setup is a Athlon64 3200+ system. Software is to be compiled when needed as it comes out of the ports collection. If I avoid the above mentioned compatibility options, is the Linuxulator in AMD64-FreeBSD 64Bit like x86_64 Linux? Assumed, I will enable IA32 compatibility, has this some performance penalties to a system running nativ 64Bit software? My intention is to avoid 32Bit software if possible (for simple testing purposes). Thanks. Oliver
