....disk performance, or run with heavy network traffic, so there are remaining issues to consider. The user level I O facilities of Mach that are used in our study are described in [Forin 91] This work is extended in [Golub 93] A shared memory interface to XII and its performance is described in [Ginsberg 93] Our XII server is a descendent of this work. 3 3. Low latency applications. A real time system that deals with temporal media should be able to provide low latency response to user input. An extreme case is a music performance system where input from a music keyboard must be routed to a ....
....could lead to higher system performance overall. 19 10. X11 Performance. Our application creates video by displaying standard X11 images at 10 frames s, thus X11 performance is a critical component. The standard socket based X11 performance was a problem, so we used a shared memory interface [Ginsberg 93] to speed up data transfers. With a standard socket based X11, we wrote a program to repeatedly call XPutImage, XFlush, and XSync, and we measured the time per frame. The display time ranged from 76 to 85ms for a 19.2KB image; in other words, we can display about 240KB s. With our shared memory ....
