I just moved to a new VPS which on paper is better than my old VPS - faster processor, more RAM, more bandwidth, etc. - but I have just discovered it all means nothing.
Apparently the only thing that really matters is how much kernel memory you are allotted when they set up the VPS
I guess this statement really was correct. I have been having problems because I keep reaching my kmemsize limit - which, it turns out is only a fraction of what I had on the old server - even though the new server's advertised specs are much better. No one advertises "kmemsize".
Perhaps the support people don't even know what it is as they keep saying kmemsize is a result of not enough ram and I need more ram (already have 50% more than on the old server).
A quick search on Google says that kmemsize is "the size of unswappable kernel memory allocated for the internal kernel structures for the processes of a particular VPS."
That does not sound like ram to me.
So, before signing up for any hosting I suggest asking about kmemsize.
