Tests with the built-in benchmarks of openssh looked rather more impressive on some of the tests, I think. If it was a 15% improvement, _everybody_ would have switched. If you have 4GB of physical memory, x86_64 gives you a large userspace memory without needing 'highmem' (32-bit userspace is limited to perhaps 3GB without highmem, depending on the motherboard), or so they tell me - I find 2GB total memory adequate.

If you are still interested, look at the x86_64 books - n32 doesn't apply, it's for mips. > > Do I have to choose one? You have to choose between x86, x86_64-64 ('pure64' - the build is not so very different from 32-bit), x86_64 (multilib - all the libraries in CLFS get built in both sizes, and working out what you need for the desktop is interesting the first time you do it, but you do get to use 32-bit browser plugins if you want to). Oh, and if you use binary graphics drivers, pure64 will probably not fit very well with them. For x86, we are usually a little nearer the sharp edge than LFS (but we haven't changed very much recently, and we don't -officially- do UTF-8, although all of my recent builds use that). > > BTW the website/documentation looks very good (apart from the missing FAQS) > But, there haven't been enough people here to ask *anything* Frequently ;) ĸen -- das eine Mal als Tragödie, das andere Mal als Farce _______________________________________________ Clfs-support mailing list [email protected] http://lists.cross-lfs.org/cgi-bin/mailman/listinfo/clfs-support
