CentOS

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....

So what differences are the kernel between Centos 6.8 and Centos 6.7 ?

We wanna update Centos 6.8 packages that some bugs were fixed to 6.7, what kind of compatibility problem would it have ?

Hi, who know the end of life for the CentOS 6.8 ?
CentOS community announced the new release of CentOS 6.9 on 5 April, 2017 and the centOS 6.8 have stopped the updates on 20 May,2017.
Might we conclude that the end of life for CentOS 6.8 is on 20 May,2017 ?
