Citrix Users EDT Performance Test
Adaptive Transport – a new transport mechanism for virtual servers is faster, more scalable, improves application interactivity, and more interactive on long-haul WAN and internet connections. When Adaptive Transport is used, ICA virtual channels intelligently switch the underlying protocol for user sessions between Enlightened Data Transport protocol and TCP to deliver faster, scalable and reliable performance.
When users have connected to the virtual desktops via EDT protocol, administrators may often want to know how the experience of each user is. This is why, the Citrix Users EDT Performance test auto-discovers the users who are logged into the virtual desktops (via the EDT protocol) provisioned using the Citrix Virtual Apps servers, and measures the bandwidth usage, packets transmission and reception, and latency of each user with the server. In the process, bandwidth-hungry, latent user sessions can be accurately isolated.
Target of the test : Citrix Virtual Apps
Agent deploying the test : An internal agent
Outputs of the test : One set of results for every user who is currently logged into the virtual desktops (via the EDT protocol) provisioned using the Citrix Virtual Apps servers.

Measurement | Description | Measurement Unit | Interpretation |
---|---|---|---|
Number of sessions |
Indicates the number of sessions intiated by this user. |
Number |
The value 0 indicates that the user is not currently connected to the Citrix server. |
Bandwidth |
Indicates the bandwidth usage of all sessions of this user. |
Kbps |
Compare the value of this measure across users to know which user is consuming the maximum bandwidth. |
Round trip time |
Indicates the round trip latency between the virtual machine and this user. |
Seconds |
Comparing the value of this measure across users will enable administrators to quickly and accurately identify users who are experiencing higher latency when connecting to a virtual machine via EDT protocol. |
Flow window |
Indicates the size of the flow window. |
KB |
The flow window and congestion window are used to control the congestion in the network. The smaller the value of both the windows, the data will be sent without any delay. The larger the value, the data will be added up in the sent queue and it will be sent with delay. |
Congestion window |
Indicates the size of the congestion window. |
KB |
|
Sent packets |
Indicates the number of EDT packets sent by this user. |
Packets |
|
Received packets |
Indicates the number of EDT packets received by this user. |
Packets |
|
Retransmitted packets |
Indicates the number of EDT packets that were retransmitted by the user. |
Packets |
|
Lost sent packets |
Indicates the number of packets lost by this user during transmission. |
Packets |
Ideally, the value of this measure should be zero. Comparing the value of these measures across users will enable administrators to quickly and accurately identify users who have extensively lost packets during transmission and reception of packets via EDT protocol. |
Lost received packets |
Indicates the number of packets lost by this user during reception. |
Packets |
|
Sent acknowledgements |
Indicates the number of acknowledgements that were received by this user for sending the EDT packets. |
Number |
|
Sent negative acknowledgements |
Indicates the number of negative acknowledgements that were received by this user for sending the EDT packets. |
Number |
|
Received acknowledgements |
Indicates the number of acknowledgements that were received by this user for reception of EDT packets. |
Number |
|
Received negative acknowledgements |
Indicates the number of negative acknowledgements that were received by this user for reception of EDT packets. |
Number |
