No. See http://themes.freshmeat.net/articles/view/709/ for a discussion, which also links to http://www.suse.de/~aj/linux_lfs.html > 2. Does NFS has that limit ? I highly doubt it, but I do not have conclusive evidence. > 3. Since 32bit span is 4G ( 2^32 ) why do I always hear about 2G > limitations ( Virtual memory & files so far ) For files, the issue is signed vs. unsigned variable types. If the type is signed, you lose one bit for the sign, and you're stuck with 2^31. For virtual memory, I've never heard of a 2 GB limitation (4, definitly, 3 or 3.5, or even 2.9, fine[0]). References? [0] In linux, the kernel is always mapped at the top of the address spae, taking anywhere from 1.1 to 0.5 GB of memory for itself. Just how much depends on the kernel version and the options it was compiled with. -- Muli Ben-Yehuda http://www.mulix.org http://www.livejournal.com/~mulix/
