To improve traffic throughput, you should strongly consider configuring the MTU size to at least 9000 bytes. When adjusting the MTU packet size, you must also configure the entire network path (VMkernel ports, virtual switches, physical switches, and routers) to support the same MTU packet size.
To increase the MTU size via CLI OpenStack CLI use the following command # openstack network set --mtu 8950

microHOWTO: Change the MTU of a network interface A common reason for wanting to increase the MTU of an interface is to improve the throughput of high-speed Ethernet. The standard Ethernet MTU has remained fixed at 1500 bytes for backward compatibility with 10 and 100 megabit networks, however this is far from optimal at speeds of 1 gigabit and above.

OpenStack Docs: MTU considerations
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. As a rule of thumb, a larger MTU size will increase bulk protocol throughput. Fewer packets with the same amount of data are processed when the MTU size is increased. However, the tradeoff is that may lead to delays in subsequent packets, resulting in lags and minimum latency. Jun 21, 2020 · How to change MTU size in Windows 10. I was doing some troubleshooting and wanted to change the MTU size. Here are the easy steps I took to do it in Windows 10. Open a command prompt as administrator. (Hit Windows start button, type CMD, right click on command prompt and run as administrator) type the command : netsh interface ipv4 show Another method to handle the increase in MTU size due to encapsulation and the resulting fragmentation is to utilize the TCP Maximum Segment Size (MSS) parameter. The MSS is the largest amount of Oct 22, 2009 · Remember that both sides needs to support this MTU or else fragmentation will occur! Try your setting out by pinging with a specific MTU: ping -s [MTU-28] -M do [ip-address] Remember to substract 28 from the set MTU giving space for headers. If packets are dropped or messages about fragmentation is recieved, lower MTU size further.
