While it is true that VPSs don’t allow you to constantly use 100% CPU, this should not be a problem, as you’re not supposed to CPU-mine anything. Not only is CPU mining bitcoins terribly inefficient as of 2017, but it has nothing to do with maintaining a wallet. It is true that while synchronizing the blockchain the wallet uses the CPU a bit more as it is confirming blocks, but after it synchronizes, CPU usage should be minimal.
If the box is still showing then that means that for whatever reason the wallet is still not connecting. Have a look at the adapters page, and specifically at the status column for your bitcoin adapter. There should be more information about why the plugin is not connecting.
