Hi -
In some kernel versions the SHMLBA is defined as
1MB(1024*1024) and in some as 16K. What would be the
difference between aligning the shared memory segment
size on 1MB versus 16K before calling shmget()? Would
there be any performance gain/lose? We are aligning
the segment address on 1MB.

thanks,
Umut
