installed centos7 latest on both systems:
[dual] E5-2620 has all mem slots populated with DDR4 2133 - SSD+HDD for storage
[single] Platinum 8168 has all mem slots populated with DDR4 2666 - optane+ssd for storage
the Platinum 8168 gets from 3x to 10x better sysbench results than the older dual cpu system
one benchmark where it fails is memory read, where dual E5-2620 cpu gets lets say 70K points and the Intel 8168 gets like 50K points.
dual cpu has each cpu with 4 channels, the single cpu has 6 mem channels
will do an SQL test next , but i’m concerned since i work with inodb tables stored in memory , so memory read speed is important,
does those results look strange or normal ?
PS: tried rhel8 beta with kernel 4.18 but that gets even lower scores than centos7 latest.
