The maximum transmission unit (MTU) is the largest size frame (packet), specified in bytes, that can be sent over a network interface. The MTU is a configurable setting. The default MTU used on Azure VMs, and the default setting on most network devices globally, is 1,500 bytes.
A speed test provides diagnostic information about the speed of the network connection between two devices. This speed test will measure the network speed between your device and the MTA datacenter. About. This site uses cutting-edge WebRTC technology to check your Internet connection's packet loss, latency, and latency jitter in your browser for free. These problems can all be caused by various similar issues, which hopefully you will be able to find and fix using this easy way to test for them. Note: cFosSpeed's MSS (MTU) optimization may reduce you MSS/MTU from 1492 to a little lower value.With ATM based DSL networks this can result in higher throuput, even if some "net speed test" pages say otherwise. MTU is measured in bytes, so a setting of "1600" would equal roughly 1.5 KB per packet. For various reasons, setting the MTU at different levels can have a dramatic effect on your Internet access

Use the ping test to test your MTU size. You want to make sure that you find the maximum packet size that is transmitted without fragmentation. Add 28 to the number you find in your ping test to get your complete MTU size.
Internet speed test statistics for hostname mtu-net.ru. Calculated average, median, lower quartile and upper quartile for download speed, upload speed and ping. Most common download speed on this hostname is 10,65 Mbits. Most common upload speed on this hostname is 0,34 Mbits. Most common ping value on this hostname is 54,00 ms. MTU Test in a non-VPN Environment. Example: Ping -f -l 1464 www.yahoo.com. If the ping is successful (no packet loss) at 1464 payload size, the standard MTU will be "1464 (payload size) + 20 (IP Header) + 8 (ICMP Header)" = 1492. 1464 Max packet size from Ping Test + 28 IP and ICMP headers 1492 is your optimum MTU Setting Internet Speed Test. In the past 30 days over people have used speed tests to see their download speeds, upload speeds, and ping.Press "Start Test" below to get started testing your connection. 3. Our MTU size is 1500 which is the default MTU size on most systems. Change Windows MTU Size. 1. Open a Command Prompt CMD (Right Click CMD -> Run Ad Administrator) 2. Type the following commands in order. netsh interface ipv4. 3. Your command window will now be at the prompt to change MTU using the next command below. 4. Check the value of the MTU is proper, this value depends on your ISP, you can ask for your ISP to get an accurate value. You can find it in “ system settings ”-> “ WAN settings ”-> “ MTU ”. Packet size, often referred to as MTU (Maximum Transmission Unit) is the greatest amount of data that can be transferred in one physical frame on the network. For Ethernet, the MTU is 1500 bytes, for PPPoE 1492, dial-up connections often use 576.
