A 10Gbps dedicated server has ten times the nominal network capacity of a 1Gbps server, but it will not automatically make your website ten times faster. Choose between 1Gbps vs 10Gbps dedicated servers by checking peak traffic, transfer windows, storage performance and the provider’s bandwidth terms.
This guide explains when each connection makes sense, how to calculate transfer requirements and what to ask before ordering an unmetered dedicated server.
1Gbps vs 10Gbps dedicated servers: the key differences
| Comparison | 1Gbps | 10Gbps |
|---|---|---|
| Nominal rate | 1,000 megabits per second | 10,000 megabits per second |
| Byte equivalent | 125MB/s | 1,250MB/s |
| Ideal time for 1TB | 2 hours 13 minutes 20 seconds | 13 minutes 20 seconds |
| One-direction capacity over 30 days at full rate | 324TB | 3,240TB (3.24PB) |
| Possible fit | Moderate traffic and longer transfer windows | Large transfers and high aggregate throughput |
These are mathematical limits, not measured OVHSAS results. Units are decimal: 1TB = 1,000GB and 1GB = 1,000MB. Real transfers take longer because of protocol overhead, congestion and endpoint limits. Monthly transfer allowance is a separate plan condition.
Port speed, bandwidth and monthly traffic are different
Port speed is the nominal rate of a network interface or service connection. Throughput is the rate your application actually achieves. Traffic allowance is the amount of data included in the billing period.
A server can have a 10Gbps interface and a much smaller guaranteed public-internet rate. It can also have a fast private network between servers while its public network uses a different connection. Check which figure the provider is advertising.
Unmetered does not remove the port limit
An unmetered plan generally bills access at a stated rate without a fixed transfer quota, subject to its terms. A metered plan includes a data allowance and may charge for additional transfer. A burstable plan can use a separate billing model.
Provider policies differ. Keep the service’s transfer quota, traffic accounting and excess-usage terms separate from its port speed. Confirm whether the contract counts incoming traffic, outgoing traffic or both.
A 10Gbps uplink is not necessarily sustained 10Gbps throughput
AWS explains baseline and burst network bandwidth for EC2 instances. A published maximum can differ from the rate available continuously. This cloud example illustrates why bandwidth specifications need context; it is not a specification for OVHSAS dedicated hardware.
Billing policies differ for traffic. Verify current terms for your chosen product before ordering.
Microsoft’s Azure network-throughput documentation explains that a VM’s outbound allowance applies across its network interfaces. Adding interfaces does not automatically increase that allowance. This is an Azure-specific example of checking service limits rather than relying on interface labels.
For OVHSAS, confirm the dedicated server’s public and private network allocations directly.
Calculate how much bandwidth you need
Start with the size of a transfer and the time available:
Required average Gbps = data in decimal GB × 8 ÷ seconds available
To move 1TB in one hour, the calculation is 1,000 × 8 ÷ 3,600 = 2.22Gbps, before overhead. A 1Gbps connection cannot complete that task within the hour. A 10Gbps connection provides nominal capacity, but both endpoints and the route must sustain the required rate.
For monthly transfer, average Mbps = monthly TB × 1,000,000 × 8 ÷ seconds in the month. Moving 20TB over a 30-day month averages about 61.7Mbps. That looks modest, but the same data concentrated into short backup windows could require a much faster connection.
Worked example: a nightly backup window
Suppose you must transfer a 500GB backup within two hours. The minimum average rate is 500 × 8 ÷ 7,200 = 0.556Gbps. A 1Gbps service might fit if real throughput and competing traffic allow enough headroom. If the window shrinks to 30 minutes, the requirement becomes about 2.22Gbps before overhead, making a faster service worth evaluating.
Use the data actually transmitted after compression or incremental processing. Check restore times too: recovering data can have a different bottleneck from uploading a backup.
When is a 1Gbps dedicated server enough?
Consider 1Gbps when measured peak usage is comfortably below the service’s achievable throughput, transfers fit their windows and your application is limited by something other than networking. A business site with small pages and effective caching may gain more from reducing slow database queries than upgrading its port.
Do not estimate solely from visitor count. Average response size, simultaneous activity, caching and downloads all change network requirements. Monitor throughput during your busiest periods and retain headroom for growth and operational tasks.
When should you consider a 10Gbps dedicated server?
Consider 10Gbps when a measured network bottleneck delays work: large backups, software distribution, media delivery or many simultaneous transfers can justify it. A fast connection can shorten transfer windows when disk, CPU and receiving systems keep up.
Check storage throughput before upgrading. A single disk that cannot feed data fast enough will limit transfers. Encryption, compression and network processing also consume CPU. The remote destination may have a slower connection, and network latency can affect individual flows.
A larger port does not inherently reduce latency or improve game-server responsiveness. For latency-sensitive services, assess server location, routing, packet loss and CPU performance alongside network capacity.
How to test a dedicated server connection
Test only between endpoints you own or have permission to use. Record the test time, locations, direction, software version and concurrent server load. Repeat measurements across relevant routes rather than treating one speed test as a universal result.
ESnet’s iperf3 documentation explains client/server throughput tests. On a controlled test endpoint, start the server with iperf3 -s. From the other endpoint, run:
iperf3 -c TEST_SERVER -t 30
iperf3 -c TEST_SERVER -t 30 -RReplace TEST_SERVER with your authorised endpoint. The first command measures client-to-server traffic; -R reverses the direction. Restrict test access and account for traffic charges. Compare network-only results with an actual file transfer, which also tests storage and application behaviour.
Questions to ask before ordering
- Is the advertised rate public or private, and is it dedicated, shared, guaranteed or burstable?
- Is transfer metered or unmetered, and which directions count?
- What happens if the allowance is exceeded: extra charges, rate limiting or another restriction?
- Are fair-use conditions or traffic-type restrictions relevant to your workload?
- Can you test routing and throughput to your users’ locations?
- What are the upgrade cost, lead time and migration requirements?

Compare the current OVHSAS options
Browse OVHSAS dedicated servers, then confirm the exact network allocation, location and billing conditions on the order page. Ask OVHSAS support about your required sustained throughput and transfer window. This comparison does not imply that every configuration includes a 10Gbps option or guaranteed public throughput.
Frequently asked questions
Is 10Gbps ten times faster than 1Gbps?
Its nominal rate is ten times higher. An application achieves that improvement only when the network is the limiting factor and the entire transfer path supports the higher rate.
How many MB/s is 1Gbps?
1Gbps equals 125MB/s before protocol overhead. A 10Gbps connection equals 1,250MB/s using the same decimal units.
Does a 10Gbps port include unlimited data?
No. Port speed and transfer allowance are separate specifications. Read the traffic policy and any excess-usage charges.
Will a 10Gbps server improve website rankings?
A port upgrade alone does not establish a ranking benefit. First measure user-facing performance and identify whether networking is the actual bottleneck.
