Hi, Group!
What caused to limit the maximum of data 8Gb for amd64 architecture?
Where we may have difficulty if to increase this value to 16-20GB?
I've edited /sys/arch/amd64/include/vmparam.h for
#define MAXDSIZ ((paddr_t)16*1024*1024*1024) /* max data size */
Now system works and allows to create mfs volumes more than 8Gb
which significantly accelerates compilation.
