Description:
Hi,
it's a mistake in 18.4.4. Linux huge pages (also in 9.4 and 9.5
documentation). Example how to count number f huge pages says:
6490428 / 2048 (PAGE_SIZE is 2MB in this case) are roughly 3169.154 huge
pages, so you will need at least 3170 huge pages:
It's very rare that PAGE_SIZE is 2MB. It's more common situation that the
value is 4096KB. But it's not a problem.
The VmPeak should by divded not by PAGE_SIZE but by Hugepagesize listed by
cat /proc/meminfo | grep Hugepagesize.
