I've ported xosview to GNU/Hurd and had a look during a gcc compilation:
approximately only half the memory is used. I had a look at
vm/vm_pageout.c and noticed:
/* When vm_page_external_count exceeds vm_page_external_limit,
* allocations of externally paged pages stops.
#define VM_PAGE_EXTERNAL_LIMIT(free) ((free) / 2)
#endif /* VM_PAGE_EXTERNAL_LIMIT */
Does Mach really need half the memory just for itself? I'd say most
memory is for user space: libraries, pictures, ... This limit probably
needs tuning (or even disabled), at least in Debian.
