Digital Equipment Corp, Hewlett-Packard Co, IBM Corp, Network Computing Devices Inc, Sun Microsystems Inc and Tektronix Inc have put their weight behind a new measure of X-server performance. Xmark performance ratings, say the companies, who got together at Network Computing Devices last month to endorse the new rating, will give a more balanced view of overall X-server performance than the usual XStone measurement, which is biased towards text scrolling and terminal emulation. The Xmark rating is a composite benchmark of results from the X Performance Characterisation group’s X11perf data. The Sun Sparctation 1 is used as a normalising system and has an Xmark rating of 1. Tektronix, with its newly launched 350 Series, currently leads the way with an Xmark rating of 2.31, followed by the NCD 19c (1.55), HP 700/RX (1.41), the Tektronix XP330 (1.40) and DEC VXT2000+ (1.27).
