Hello, Thank you for posting in Q&A forum. Exacly, as you mentioned above, TCP buffer size is a crucial parameter that can affect the performance of a Windows server. While increasing the TCP buffer size can improve network throughput and reduce packet loss, it can also lead to increased memory usage. In most cases, the default TCP buffer size settings provided by the operating system are sufficient for general use. If you want to make additional change, it is recommended to review the Microsoft Official Documentation to understand when they are beneficial and how they apply to your network environment.
