I am starting out with a brand new and crispy fresh 1024mb Linode. This will run a single Xenforo forum. I see that the minimum CentminMod requirements for CentOS 6.5 is only 256mb of memory, but is 1024mb memory for 7. With only having a 1024mb Linode (unfortunately can't afford the 2048mb plan) is it recommend to go with CentOS 6.5 over 7 due to memory limits? Or are there enough improvements to warrant running 7 with only 1024mb?
