Configure the network packet size Server Configuration Option. 03/02/2017; 2 minutes to read +5; In this article. Applies to: SQL Server (all supported versions) This topic describes how to configure the network packet size server configuration option in SQL Server 2019 (15.x) by using SQL Server Management Studio or Transact-SQL. In computer networking, the maximum transmission unit (MTU) is the size of the largest protocol data unit (PDU) that can be communicated in a single network layer transaction. The MTU relates to, but is not identical to the maximum frame size that can be transported on the data link layer , e.g. Ethernet frame . 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. 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.

The MTU size is restricted to prevent an ICMP-based attack. An ICMP-based attack could reduce the MTU size to very low value. A very low MTU size could cause a severe decrease in performance. However, an MTU size that is restricted to 576 bytes may affect certain WAN scenarios, such as satellite links. In these WAN scenarios, the MTU size might tcpip - How to increase MTU size on Linux 2.6? - Server Fault How to increase MTU size on Linux 2.6? Ask Question Asked 11 years ago.

I've added NUS service to my app (nRF52832, peripheral, FreeRTOS based, SDK 15.2, SD132). everything works great with MTU size = 23 bytes. Now I try to increase the MTU size to 247 like in the example:
