Nope. We didn't move to the 32 GB server. I ordered it and set it up the same was but the server had issues. First we were getting segmentation faults and they replaced the memory and then I had it all setup and copied over and the settings between the two matched exactly, and the other server was slower than the old server.
We were using APC caching on the old server and now are using Opcache which is supposed to be (and seems to be) much better.
So we are only on 16 GB of ram... and doing very well.
Oh one thing I am doing now which may slow things down is I am rebuilding the cache of all attachments, which has not been done since we moved to Xenforo. But if things slowed down they will be back to its fast self in a few hours.
