Obtaining Peak Skype for Business (Lync) Performance
This article addresses some of the factors that impact Skype for Business (Lync) performance. Many of these factors contribute to or take away from optimum Skype for Business audio and video performance and ultimately the quality of your Skype for Business experience. These factors can be summarized in the following categories:
If possible, ensure your device is a recent model and up to date. Hardware platform, processor, memory and video processing capacity all impact performance. In addition, make sure that you have a current operating system (OS) installed and that you are up to date with all patches, updates and service packs.
The Skype for Business Client
Your Skype for Business client determines the feature set you have available. Make sure that you have the most current client for your platform (how do I know? – link to another article) and that you have applied all the available updates.
Environmental noise and poor lighting can contribute to our perception of a poor quality Skype for Business experience. If possible, move to an environment more conducive to improving your Skype for Business experience.
Network connectivity is one of the most critical factors as well as the most common cause of problems impacting Skype for Business performance. Where are you located? Are you connected to a wired or a wireless connection? Do you have enough bandwidth (information carrying capacity)? Is the network congested (busy)?
Skype for Business (Lync) users moving from a wired connection to wireless will be dropped from their active Skype for Business session. This can also occur for users when roaming on wireless networks when the individual moves from one wireless access point to another.
The loss of the Skype for Business session is due to normal network behavior and is not a Skype for Business issue. The Skype for Business user will have to rejoin the session. For best performance, ITS recommends staying in the same location if you have an active Skype for Business session such as a Skype for Business meeting or chat session.

Assuming that your device and Skype for Business client are up to date and operating at peak performance and that you are in an environment that optimizes your Skype for Business experience, your quality of experience will be determined by the Skype for Business modality you are using (chat, audio, video, etc.) and the type of network connection you have (wired, wireless, onsite, offsite, etc.) The following matrix will help you determine the quality of experience you can expect in a variety of environments. This legend will help explain the experience you should expect:
Recommended = Best or good quality of experience
Acceptable = Average quality experience, dependent upon available bandwidth and network congestion

(1)Current device, OS and current Skype for Business Client recommended
