Better performance

GDDM V3R2 General Information
GC33-0866-03

Several enhancements have been made to GDDM-OS/2 Link to improve its windowing performance. Chief among these are:

Much improved speed of picture redraw: GDDM-OS/2 Link can now create a bit map for each host session and restore the screen when necessary by redisplaying the bit map. Though the initial drawing of the bit map can add to the performance overhead, subsequent screen-redraw operations are instantaneous. This method of creating and maintaining the screen contents is optional.
Reduced memory and disk requirements for running GDDM-OS/2 Link. The run-time size of GDDM-OS/2 Link has been reduced by approximately 120KB.
Reduced initialization time.
Reduced service-update time.
