Performance Metrics for Browser Based Gateway
The Browser Based Gateway can support multiple sessions, and below is some information and statistics to help you determine what hardware requirements you will need.
CPU Usage
Primarily the CPU on the server where the gateway is installed is the hardware which performs a majority of the work. The minimum requirement for 400 concurrent connections is Pentium Dual-Core 2.7GHz, and usually adding in one more CPU will support up to another 300 – 400 concurrent RDP sessions.
Memory Usage
The Gateway is light on memory usage, and 250mb is usually enough to support 300 concurrent sessions
Bandwidth Usage
Bandwidth usage can be very different depending on the content. As the Browser Based Gateway is based on the standard RDP protocol, information about this can be found in the Microsoft white paper:
From our testing and customer response, one RDP session needs about 260 Kbit bandwidth for normal business applications (Office, ERP etc).
