cat /proc/meminfo | grep Huge
HugePages_Total: 1024
HugePages_Free: 1024
HugePages_Rsvd: 0
HugePages_Surp: 0
Hugepagesize: 2048 kB
發現是2M大頁內存
改問1GB大頁內存
設置1GB大頁內存 /etc/default/grub中的GRUB_CMDLINE_LINUX 加上transparent_hugepaage=never default_hugepagesz=1G hugepagesz=1G hugepages=32
然後#grub2-mkconfig -o /boot/grub2/grub.cfg
#reboot
cat /proc/meminfo | grep Hugepagesize 是1048576 kB
