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. */ #ifndef VM_PAGE_EXTERNAL_LIMIT #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.
