1440 Max packet size from Ping Test + 28 IP and ICMP headers. 1468 Your optimum MTU Setting . In your case if the maximum packet size is 1452 the optimal MTU (Maximum Transmission Unit) is 1452+28 i.e. 1480. Here 1452 is the packet size of the data sent but the MTU is 1480. Hope this information is helpful. Amrita M. Microsoft Answers Support
No, there is no universal optimal byte size. TCP packets are subject to fragmentation, and while it would be nice to assume that everything from here to your destination is true ethernet with huge packet sizes, the reality is even if you can get the packet sizes of all the individual networks one of your packets takes, each packet you send out may take a different path through the internet. Dec 13, 2018 · The recommended size is either 512 or maybe even 1024 - you can go up to 2048 if you have enough RAM to support it. Ensure that the transmit buffer is double the receive buffer. As the name implies, MTU refers to the largest data packet that can be carried over your network pipe. MTU is measured in bytes, so a setting of "1600" would equal roughly 1.5 KB per packet. NOTE: Since you got a reply, take 1472 and add 28 to it for you to get the correct MTU size. In the example given above, 1472 is the proper value and the size would be 1500 for the network you’re working with. Setting up the correct MTU size. After getting the correct MTU size, do the following: Step 1: MX Series. PPP MTU and MRU for PPPoE Subscribers, PPP MTU and MRU for Tunneled Subscribers on LNS In order to minimize packet latency, I'm not considering TCP/IP. But, I wish to maximize the throughput uisng UDP. What should be the optimal size of UDP packet to use? Here are some of my considerations: The MTU size of the switches in the network is 1500. If I use a large packet, for example 8192, this will cause fragmentation. Mar 23, 2017 · Once the Command Prompt is open, follow these steps to change the MTU size: Type ‘netsh interface ipv4 show subinterface’ then press enter. You will see a list of network interfaces. There should be one that is clearly your NIC interface, often blatantly labeled as “Ethernet”. Take note of this name.
Online MTU test allows you to test the maximum MTU size from our host to your destination. To check your MTU, simply provide your IP or DNS hostname. We will test the PMTU (Path Maximum Transfer Unit) aka maximum MTU size (unfragmented) between our host and your destination, most likely the outside of your router or firewall.
May 21, 2013 · MTU Rate: This may vary depending on who your DNS server is with, but for Google's (8.8.8.8 and 8.8.4.4), your MTU Rate should be set to 1500. It determines how large your packets are before fragmenting, so your packet size would be 1472 + 28 for the IP header. Nov 28, 2016 · The maximum size of frames is called the Maximum Transmission Unit (MTU). When a network device gets a frame that is larger than its MTU, the data is either fragmented into smaller frames, or dropped. Historically, Ethernet has a maximum frame size of 1500 bytes. An Ethernet packet larger than 1500 bytes is called a jumbo frame. One method to test and detect a reduced MTU size is to use a ping with a large packet size. Here are some examples of how to do this. C:\Users\ScottHogg> ping -l 1500 192.168.10.1
How can I optimize PPPoE connections? | SonicWall
The Maximum Transmission Unit (MTU) is a parameter that limits the largest size a network layer packet can have when being encapsulated into a frame. In IP networks using Ethernet, this maximum size is 1500 bytes by default. May 21, 2013 · MTU Rate: This may vary depending on who your DNS server is with, but for Google's (8.8.8.8 and 8.8.4.4), your MTU Rate should be set to 1500.

Here are some examples of how to do this. C:\Users\ScottHogg> ping -l 1500 192.168.10.1 Increase MTU size for the network interfaces. For the Gigabit Ethernet adapter, use the device attribute jumbo_frames=yes to enable jumbo frames (just setting MTU to 9000 on the interface is not enough). Refer to: TCP and UDP performance tuning
