etc. I've seen several big machines go from a few thousand tps to 15
to 20k tps just from going from 3.2 to 3.13. Keep us updated on
whether or not a pooler works for you.I'm running a CentOS 6.6 with Kernel 2.6.32-504.el6Is it possible to upgrade to the 3.13 version using Centos 6.6? (I think only in Centos 7)Is so, can you please provide me any link that shows a IO improvement between two kernels? something that I can study
