There are various reasons for slowing down RDP servers and you can overcome them by knowing them all and getting a good performance from the RDP.
1. Bandwidth: The RDP requires sufficient bandwidth to connect and run. It means your local internet connectivity should be good and latency should be low.
2. Hardware: The hardware specifications of the device you're using to connect to the remote server can impact RDP performance. If your client's device is outdated or lacks the necessary processing power, it may struggle to render the remote desktop environment efficiently. So, you need good and updated hardware to take out RDP performance.
3. Outdated OS on Local Computer: Using outdated versions of Windows OS and Remote desktop application software can lead to compatibility issues and suboptimal performance. Always keep your PC OS and Remote desktop application up-to-date to benefit from performance improvements and security fixes. Regularly updating both the client and server operating systems with the latest Windows updates and patches can help to gain good performance of the RDP.
4. Running Unnecessary Application: Other running applications or background processes on either the client or server can consume system resources, causing RDP slowdowns. Close unnecessary applications or services that may be competing for resources.
5. Multiple RDP sessions: If multiple users are working simultaneously and connected to the same remote server via RDP, the server's resources (CPU, RAM, etc.) get divided among users, resulting in reduced performance for each session. Be sure that the server can handle the number of concurrent RDP connections effectively.
6. Monitoring over usage (RAM and CPU): The performance of the RDP plays a crucial role in RDP responsiveness. If the applications are overloading or it is under heavy load, the RDP may struggle to handle the RDP session effectively. Monitoring server CPU, memory, and disk usage can help identify performance bottlenecks.
7. RDP under attack: In an increasingly interconnected computer the attackers use brute-force technique and repeatedly try different username and password combinations to gain unauthorized access to an RDP server. Each login attempt consumes server resources (CPU and RAM) which overload the RDP, causing it to slow down or become unresponsive. Brute-force attacks involve a high volume of login attempts, which can lead to increased network traffic. This surge in traffic can saturate the available bandwidth, potentially affecting the performance of other network services and users. Legitimate RDP users may experience slowdowns or disconnections due to the congestion caused by the attack.
By taking steps to address latency, packet loss, bandwidth constraints, and other issues related to your internet connection, you can improve the overall quality and responsiveness of your RDP sessions.
