Pfff. Try harder linode. # grep MHz /proc/cpuinfo cpu MHz : 3922519.116 cpu MHz : 3922519.116 cpu MHz : 3922519.116 cpu MHz : 3922519.116 T

That's only 4 cores. I'd rather have the cores.

  They could flip a switch tonight and tell you you've got 128 cores. That doesn't mean those cores are going to do you any good. Linode is the only VPS I've seen that gives a gross number of cores to everyone. Instead of allocating a cpu count correlated somewhere along side plan-tiering, they just give everyone a lot of CPUs (8), and then they use tiers to determine priority, who gets to actually use those cores. An entry level plan has 1/16th the CPU priority of a top tier user, and pays 1/16th as much and has 1/16th as much ram. If you're not RAM bound, for a somewhat loaded system you'll see slightly better than linear scaling (since you aren't paying as many context swaps) as you move up in tiers. I think it's a really bad policy to give entry level users scheduling on so many cores: their workloads will never stick on a local cache! Their jobs are going to be bouncing around the system getting evicted from everywhere and bouncing to the next place where they can trash it's cache next. This is a marketing gimmick, a "our number is higher" trick, played on people like you jedbblue! Some time in the past: the Pentium IV netburst core was going to hit 4GHz, then 5GHz. The mhz wars were on, mhz sold, they were what people saw, first and foremost, and it's more the fact that the insanely-deeply-pipelined core didn't even scale that scrapped the idea than people wizening up. I'm not sure if Linode's scheme here is as bad as all that, but it seems unnatural to me, and I certainly would not consider 8 cores to be a boon in this circumstance. Edit- this does change things a good bit! A quote from elsewhere in this thread I was not aware of- We limit the number of Linodes placed on each host machine. We also only place one plan type on each host. In the worst-case scenario, you're splitting CPU time evenly with your fellow Linoders, but are still able to use the full potential of the host if others are idle. This is a little different circumstance than what I'd guessed at above as you're not going to be outclassed by higher tiers, you just have to play with peers, and pay to have less of them.

    Yup, I've tried many over the years and Linode is the best I've found. :)
