We did the performance testing between CentOS7.4(kernel-3.10) and CentOS6.9(kernel-2.6) with the tool(UNIX benchmark-5.1.3) ,however the results show that CentOS7.4 got a almost 7% downgrade compare with CentOS6.9.
So I wanna know the detail reasons ,maybe there are some problems for my test method.
If U have any suggestion or know the details ,please show your comments follow it.
Thanks.
Who knows the official performance testing report of Centos 7.4?

If your test is with latest updates of CentOS7.4 - then you are observing the performance hit by the Spectre/Meltdown fixes. You can disable them and try the bench again.
