No, CPU seems to be an exception. Even on the smallest plan, you can often burst all the way to 400% (4 cores). So it depends on what other customers are doing,

No, CPU seems to be an exception. Even on the smallest plan, you can often burst all the way to 400% (4 cores). So it depends on what other customers are doing, and if everyone else were idle, you'd get the same CPU in both plans. But the host machine is at least an 8-core beast, so one person bursting to 400% doesn't affect other customers as much as it would in other hosting platforms. Also, the main bottleneck in a VPS setup is RAM and I/O. Personally, I've never had a CPU shortage in the two years I've been with Linode ;)
