Assessing Your Environment

Before you can optimize the performance of your RDS environment, you need to understand its current state. This includes identifying the hardware and software components of your RDS infrastructure, as well as the performance metrics that are most relevant to your business. Some of the key performance metrics to monitor include: 

  • CPU Usage: High CPU usage can cause delays and responsiveness issues in RDS environments.
  • Memory Usage: Insufficient memory can cause RDS servers to slow down or crash.
  • Network Latency: High network latency causes delays in screen updates and input responsiveness. 
  • Disk I/O: Slow disk I/O causes delays in application launches and file transfers. 

To assess your RDS environment, you can use Microsoft’s built-in performance monitoring tools, such as Performance Monitor and Resource Monitor. These tools provide real-time and historical data on CPU, memory, network, and disk usage, which can help you identify performance bottlenecks and plan for capacity upgrades. 

Optimizing Server Hardware

Server hardware is a critical component of any RDS environment. The performance of your RDS servers depends on the processing power, memory, storage, and network capacity of the underlying hardware. To optimize server hardware for RDS, you should consider the following factors: 

  • Processor: RDS servers can benefit from high-speed processors with multiple cores to handle multiple user sessions simultaneously. 
  • Memory: RDS servers should have sufficient memory to accommodate user sessions and prevent performance degradation. 
  • Storage: RDS servers require fast and reliable storage to ensure fast application launches and file transfers. 
  • Network: RDS servers should be connected to high-speed and low-latency networks to provide a smooth and responsive remote desktop experience. When accessed over the internet, the internet bandwidth must have sufficient throughput and low latency to accommodate the number of remote users. 

 

Please follow these leading practices in order to deliver great end user RDS experience: 

  • Use Dedicated Servers for RDS: avoid sharing RDS servers with other workloads to ensure consistent performance. If you must share RDS servers with other workloads, make sure that the underlying hardware has sufficient capacity in order to avoid resource contention.
  • Use SSD Storage: Solid-state drives (SSDs) offer faster read/write speeds than traditional hard disk drives (HDDs), which can improve application launch times and file transfers. 
  • Use High-Speed Network Adapters. Gigabit Ethernet adapters can provide faster data transfer rates than standard Ethernet adapters. This can reduce network latency and improve screen refresh rates.
  • Server Density: Make sure to properly size the RDS servers with RAM and CPU that is required for the total number of users to do their work productively. In some cases, it is better to spread the load across multiple servers rather than add more RAM and CPU to cramp more users on one server. Proper testing and performance measurement will help guide the best configuration between scaling up resources or scaling out servers.
  • Use high-speed internet. A high-speed, low latency internet connection is a must for remote workers. Ensure that there is at least available bandwidth of 100Kbps per user for common usage. If conducting CAD and graphical work on RDS over the internet, plan for at least 1Mbps per user of available bandwidth.

Configuring RDS Settings

RDS settings can have a significant impact on performance and user experience. To optimize RDS settings for the enterprise, you should consider the following factors:


  • Session timeout: Configure session timeouts based on your organization’s security policies and user behavior. Longer timeouts can improve user productivity but increase the risk of server over-utilization.
  • Screen resolution: Set appropriate screen resolutions for user sessions based on the display capabilities of their devices. Lower resolutions can improve screen refresh rates and reduce bandwidth usage. 
  • RemoteFX settings: RemoteFX is a set of features in RDS that improves the performance of graphics-intensive applications. Configure RemoteFX settings based on the graphics requirements of your applications and the capabilities of your server hardware. 
  • Compression settings: Configure compression settings to reduce network bandwidth usage and improve screen refresh rates. However, higher compression settings can increase CPU usage on RDS servers.
  • Cache Bitmaps: Enable Bitmap Caching in order to reduce the amount of data that needs to be sent between the end user and the RDS server. This significantly improves the performance and responsiveness of remote desktop sessions and reduces the amount of data that needs to be re-transmitted.
 

To configure RDS settings, you can use the Remote Desktop Session Host Configuration tool or Group Policy settings. These tools allow you to configure session timeouts, screen resolutions, RemoteFX settings, and compression settings based on your organization’s requirements. 


Network Security Best Practices for RDS

In the realm of remote desktop services, security is paramount. Given the sensitivity of the data and applications accessed through Microsoft RDS, ensuring the integrity and confidentiality of this information is crucial. Here are key strategies to bolster your remote desktop gateway
security:

Implement VPN Solutions

A Virtual Private Network (VPN) provides a secure tunnel for the transmission of data between remote users and your RDS environment. By encrypting the data in transit, a VPN ensures that sensitive information remains confidential and secure from potential eavesdropping.

Deploy Firewalls Strategically

Firewalls act as gatekeepers for incoming and outgoing network traffic. To protect your remote desktop services setup, configure both perimeter and host-based firewalls to enforce strict access controls. This includes defining rules that only allow RDS traffic from known IP addresses and blocking all unnecessary ports and protocols.

Utilize Encryption Protocols

Encryption is a non-negotiable aspect of network security. Ensure that all communication between RDS clients and servers is encrypted using strong protocols like TLS (Transport Layer Security). This applies not only to the initial connection but also to the data being transmitted during remote sessions.
