Davidson College Virtual Lab User Guide

Davidson College’s Virtual Lab provides faculty and students remote access to many of the computer lab resources that are on campus. This allows students to utilize applications and resources that may not be available on personal devices due to licensing or computer resource limitations. You can access the Virtual Lab using your preferred web browser. Please note that software that runs exclusively on Apple Macs is not available through Davidson College’s Virtual Lab.

Network Speeds & Guidelines

To ensure an optimal experience with Davidson College’s Virtual Lab, make sure you have a high bandwidth, low latency Internet connection. If you have a poor network connection, response times may be slow and images may appear pixelated. The use of personal hotspots is not recommended as they may not be reliable.

• For most applications, performance is good over WiFi if latency is less than 100ms. Bandwidth is typically not a limiting factor.
• For graphics-intensive applications, like ArcGIS, we recommend using a wired network connection instead of WiFi, ideally with a bandwidth of 1 Mbps or greater and latency less than 50ms.
• For video, we recommend a bandwidth of 3 Mbps for regular video or 5 Mbps for HD and latency less than 50ms.
• Wired connections can improve your experience using Davidson College’s Virtual Lab, as using Using a hard wired network connection can reduce latency by a factor of ten

Please refer to the Speed Tests section below for additional information on how to determine if your Internet connection meets the guidelines above.

Speed Tests

Davidson College’s Virtual Lab is a hosted application running in a data center located in Virginia, which is meant to keep latency (the round trip time between your clicks and application responses) as low as possible.

• Bandwidth is likely not a limiting factor unless you are using a graphics-intensive app or streaming video.
• If you experience slow performance in Davidson College’s Virtual Lab, you may test latency and bandwidth using sites like https://www.speedtest.net or http://cloudharmony.com/speedtest-for-aws to determine whether your network connection is sufficient or not. If you use the speedtest-for-aws option, you need to allow the tests to complete to get a full understanding of network performance issues you might face.
