The gap is smaller than the price difference<\/h2>\n

A good KVM VPS already gives you root, your own operating system, and reserved memory. So what does bare metal add, and is it worth three to five times the money?<\/p>\n

The honest answer is that it depends entirely on whether your load is sustained. Bursty traffic is what virtualisation is good at. Constant heavy work is where dedicated hardware pulls ahead, and where the price starts making sense.<\/p>\n

The real differences<\/h2>\n

Hypervisor overhead.<\/strong> Small on modern processors, a few percent. Not the reason to buy metal.<\/p>\n

Disk I\/O.<\/strong> This is the big one. On a VPS the disks are shared with other tenants, so your throughput depends on what they are doing. On bare metal the drives are yours, and for a database writing constantly that difference is large and consistent.<\/p>\n

Memory ceiling.<\/strong> VPS plans top out. If your database working set is 200GB, no VPS plan holds it and every query hits disk. Bare metal goes as far as the motherboard does.<\/p>\n

Hardware control.<\/strong> RAID level, extra drives, specific CPU features. Invisible from inside a virtual machine.<\/p>\n

Predictability.<\/strong> Nobody else’s workload can affect yours, ever. Not just usually.<\/p>\n

Steal time, the number that decides it<\/h2>\n

There is one measurement that tells you whether virtualisation is costing you anything. Run top<\/code> and look at the st<\/code> column on the CPU line. That is steal time: the percentage of time your virtual CPU wanted to run and the physical host was busy with someone else.<\/p>\n

top -bn1 | head -3<\/code><\/pre>\n
Zero or near zero means virtualisation is costing you nothing and bare metal would not help. Consistently above a few percent means the host is oversubscribed and you are being slowed by other tenants. Above ten percent, moving is worth it.<\/p>\n
Check it during your busy period, not at midnight. This one number saves people a lot of money that would otherwise go on hardware they did not need.<\/p>\n
Which to choose<\/h2>\n
Choose a VPS when:<\/strong> traffic is bursty; you might need to resize; you want a new environment in minutes; the workload is a normal website; or your budget matters more than the last twenty percent of performance.<\/p>\n
Choose bare metal when:<\/strong> load is sustained rather than spiky; the database is larger than any VPS plan’s memory; disk I\/O is constant; you need a specific RAID configuration; steal time on your current VPS is consistently high; or you are running enough VPS capacity that one machine is cheaper.<\/p>\n
Cost at scale<\/h2>\n
The crossover is worth calculating rather than guessing. Add up what you currently spend on VPS capacity and compare it against a single dedicated server with the same total resources. Dedicated usually wins on raw resource per currency once you are running the equivalent of three or four mid-sized VPS instances.<\/p>\n
But add the other side of the ledger. One machine is one point of failure, where several VPS instances across different hosts are not. And a dedicated server takes hours or days to replace, where a VPS is minutes. If uptime has a price for you, that difference is part of the calculation.<\/p>\n
A common middle path is a dedicated server for the database and steady workload, with VPS instances for anything that needs to scale up and down.<\/p>\n
