I have a Sparcstation 1+ running Sun Os 4.03 and Openwindow 2.0. My feeling is that X-applications (and I mean applications which use the X server part) are quite slow. Applications which need to create DYNAMICALLY a lot of widgets (e.g 2 or 3 hundred) seem to spend a lot of time both in the toolkit and in the server. I would like to understand if the slowness is caused basically by the server implementation or is also due to the structure of the Xt toolkit. How the application performance degrades when the number of widgets to create DINAMICALLY is great? Is anyone willing to provide comments?

We found that Openwin has a problem dealing with VisibilityNotify events. Simply turning off the VisibilityChangeMask on all our widgets/windows solved the problem. Try that one out. -- ===== FOR SALOMON EYES ONLY ====== Victoria S. Drozdov Phone: (212)747-7595 Fulcrum Email: victoria@fulcrum.sbi.com One New York Plaza, 43rd floor
