system engineering, the choice between proprietary and open-source software often hinges on practicality and expertise. I&#8217;m a big supporter of open-source solutions, recognizing their potential in the right scenarios. However, this preference isn&#8217;t without its challenges. Open-source systems demand a deeper understanding, requiring time and effort that might not always be available, especially when deep-diving into complicated configuration files.<\/p><p>Currently, I&#8217;m gearing up for an upcoming session at Cisco Live. This preparation includes setting up a shared environment for users. Traditionally, I&#8217;ve relied on a Windows Jumphost for user connections.

Setting up a Windows Server with a terminal server role \u2013 a task that I quickly discarded.<\/p><p>In search of efficiency, I turned to Ubuntu 22.04, installing and initiating <strong>XRDP<\/strong>.

When set to <code>true<\/code>, it disables Nagle&#8217;s algorithm, which means that packets are sent as soon as possible without waiting to fill up the full TCP segment.

It ensures that the connection between the client and the server remains active even when there&#8217;s no data being transmitted.<\/li><li><strong>Effect<\/strong>: Prevents the connection from being closed due to inactivity, which can be important in remote desktop sessions that might have periods of no user activity.<\/li><\/ul><\/li><li><p><strong>tcp_send_buffer_bytes=4194304<\/strong><\/p><ul><li><strong>Purpose<\/strong>: Sets the size of the TCP send buffer to 4,194,304 bytes (or 4 MB).<\/li><li><strong>Effect<\/strong>: A larger send buffer can improve performance in high-latency networks by allowing more data to be &#8220;in flight&#8221; on the network. However, setting it too high can lead to inefficient use of bandwidth and increased memory usage.<\/li><\/ul><\/li><li><p><strong>crypt_level=low<\/strong><\/p><ul><li><strong>Purpose<\/strong>: This sets the encryption level for the RDP session. <code>low<\/code> means minimal encryption is used.<\/li><li><strong>Effect<\/strong>: While this setting can improve performance because of lower computational overhead, it also makes the connection less secure. It&#8217;s typically not recommended for environments where security is a concern. <span style=\"text-decoration: underline;\"><strong>This was the mosy significant tuning parameter!<\/strong><\/span><\/li><\/ul><\/li><li><p><strong>max_bpp=16<\/strong><\/p><ul><li><strong>Purpose<\/strong>: Stands for &#8220;maximum bits per pixel&#8221; and is set to 16 in this case.<\/li><li><strong>Effect<\/strong>: This limits the color depth of the remote session to 16 bits per pixel. Reducing color depth can decrease the amount of data sent over the network, improving performance, especially on slower connections.
