In this article, I will discuss the importance of setting the correct Maximum Transmission Unit (MTU) size for gaming and its impact on network performance. I will also answer common questions related to MTU sizing.
What is a good MTU size for gaming
A good MTU size for gaming should not be below 1400. It is recommended to start with a value that is successful, and then increase it by 1 until you encounter errors again.
Why set MTU to 1400
Setting the MTU size to 1400 is crucial for overlay networking and to avoid dropped packets. WireGuard, for example, sets the Don’t Fragment (DF) bit on its packets, requiring the MTU for AKS (Azure Kubernetes Service) to be set 60 bytes below the underlying network’s MTU of 1400.
Should MTU be 1500 or 1492
For a WAN interface connected to a PPPoE DSL network, it is generally recommended to set the MTU to 1492. This value is discovered as the maximum allowed MTU with auto MTU discovery. However, an MTU of 1452 is often the most optimal choice.
Is 1480 MTU good for gaming
A standard MTU for Ethernet is always around 1500, unless Jumbo Frames is enabled. If you are facing MTU-related issues in gaming, it is likely due to network adapter or router configuration problems.
Should I set MTU to 1500
The standard MTU size for Ethernet is 1500 bytes, not including the Ethernet header. Higher-level protocols must fit within this MTU. It is important to check if your specific network requires a different MTU size.
Does MTU affect speed
Yes, the MTU size of the network can significantly impact performance. Using larger MTU sizes allows the operating system to send fewer packets of larger sizes, resulting in improved network throughput.
What happens if MTU is too big
If the MTU is too large and the receiving device cannot accept it, the packet is divided into multiple packets through fragmentation. This can negatively affect performance, adding delay and extra data.
Does increasing MTU increase speed
Changing the MTU setting on your router can potentially boost network speed performance. However, it is crucial to find the optimum MTU value for your specific network to achieve the best results.
What is the best MTU value for speed
The optimum MTU value for speed is typically calculated as MTU = 1472 + 28, resulting in 1500 bytes. This accounts for the payloads, TCP, and IP headers, leaving 1460 bytes for data.
Does changing MTU size affect speed
Changing the MTU size can have a significant impact on performance. Using larger MTU sizes reduces the number of packets sent, resulting in improved network throughput and potentially increased speed.
Questions and Answers
1. What is a good MTU size for gaming?
A good MTU size for gaming should not be below 1400. Start with a successful value and increase it by 1 to find the optimal size.
2. Why set MTU to 1400?
Setting the MTU to 1400 is necessary for overlay networking and to prevent dropped packets. WireGuard sets the DF bit, requiring AKS to have a lower MTU.
3. Should MTU be 1500 or 1492?
For PPPoE DSL networks, set MTU to 1492. Auto MTU discovery often reveals this as the maximum allowed MTU. However, an MTU of 1452 can be optimal.
4. Is 1480 MTU good for gaming?
A standard MTU for Ethernet is around 1500. Issues with gaming and MTU are usually due to network adapter or router configuration problems.
5. Should I set MTU to 1500?
The standard MTU size for Ethernet is 1500 bytes, excluding the Ethernet header. Ensure your network requirements don’t deviate from this standard.
6. Does MTU affect speed?
MTU size significantly impacts performance. Using larger MTU sizes reduces packet count and improves network throughput.
7. What happens if MTU is too big?
If the MTU is too large, packets are fragmented, causing delays and additional data. Fragmentation negatively affects performance.
What is a good MTU size for gaming
You shouldn't go below 1400. When you find a value that is successful, start to increase that value by 1, so if 1462 is successful, for example, try again with 1463 etc until you get errors again.
Why set MTU to 1400
Recommended MTU for overlay networking
WireGuard sets the Don't Fragment (DF) bit on its packets, and so the MTU for WireGuard on AKS needs to be set to 60 bytes below (or 80 bytes for IPv6) the 1400 MTU of the underlying network to avoid dropped packets.
Should MTU be 1500 or 1492
It is generally recommended that the MTU for a WAN interface connected to a PPPoE DSL network be 1492. In fact, with auto MTU discovery, 1492 is discovered to be the maximum allowed MTU. However, having an MTU of 1452 is most optimal.
Is 1480 MTU good for gaming
A standard MTU is always around ~1500 for Ethernet (unless Jumbo Frames is enabled). It is just the packet size. If you are having trouble with MTU is due to the network adapter or router configuration.
Should I set MTU to 1500
Ethernet MTU
The standard size MTU for Ethernet is 1,500 bytes. This does not include the Ethernet header of 18 or 20 bytes, and is the theoretical maximum amount of data that can be transmitted by the physical link. The MTU of any higher-level protocols must fit within this MTU.
Does MTU affect speed
The MTU size of the network can have a large impact on performance. The use of large MTU sizes allows the operating system to send fewer packets of a larger size to reach the same network throughput.
What happens if MTU is too big
The MTU of the next receiving device is determined before sending a packet to it. If the packet is too large and the next receiving device cannot accept it, the packet is divided into multiple packets and sent. This is called fragmentation. Fragmentation is bad for performance, as it adds delay and extra data.
What if MTU is too high
The MTU of the next receiving device is determined before sending a packet to it. If the packet is too large and the next receiving device cannot accept it, the packet is divided into multiple packets and sent. This is called fragmentation. Fragmentation is bad for performance, as it adds delay and extra data.

Does increasing MTU increase speed
Changing the maximum transfer unit (MTU) setting on your router may boost your overall network speed performance significantly.
What is the best MTU value for speed
So, the value of MTU = 1472 + 28 i.e., 1500 byte which is the optimum MTU value. MTU consists of a payload and TCP and IP headers of 20 Bytes each that is 40 bytes in total and they are compulsory for every packet, which leaves us with 1500 – 40 = 1460 bytes of data.
Does changing MTU size affect speed
The MTU size of the network can have a large impact on performance. The use of large MTU sizes allows the operating system to send fewer packets of a larger size to reach the same network throughput.
