Upgrading of the display manger or graphical user interface at EPICS sites reliant on older display technologies, typically MEDM or EDM, requires attention not only to functionality but also performance. For many sites, performance is not an issue - all display managers will update small numbers of process variables at rates exceeding the human ability to discern changes; but for certain applications typically found at larger sites, the ability to respond to updates rates at sub-Hertz frequencies for thousands of process variables is a requirement. This paper describes a series of tests performed on both older display managers – MEDM and EDM – and also the newer display managers CSS-BOY, epicsQT, and CaQtDM. Modestly performing modern hardware is used.
