Theoretically standard 32bit can address 4gb but the kernel splits that memory space between userspace and kernel space, classically in a 2gb:2gb split, which leaves 2gb addressable memory. It is possible to set it up in a 3gb:1gb split, but it is not standard. Bigmem uses an extention that allows addressing more memory (I think that it's called pxe). Another option is to use a 64bit kernel, but unless you use a 64bit userspace a few things can cause problems (most things work ok, I think except some modules). The only problem with a 64bit userspace is more memory consuption by programs (about 15%). Performace may also vary, depending on typical usage. > Regards, > Andrei -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
