Do you setup your huge pages via the sysctl.conf file or by hand after you startup the system? One other item is I had something similar in my dual socket machine. I could only get about 12K total 2megs pages in 64G machine 32G per socket. I increase the memory per socket and that allowed me to reach 16K pages total or 8K pages per socket. I did not understand why it happened I just assumed it was how Linux used memory. Sorry this most likely does not help much. > > Thanking You, > Param. >> On 02-Aug-2017, at 11:34 AM, Kyle Larose <[email protected]> wrote: >> >> Could it have to do with memory fragmentation?
