The DECwindows X display server requires specific tuning for graphics-intensive and 3D applications because of greater demand for system resources. You may need to make adjustments for server quotas on 3D-accelerated systems. These are minimum values suggested for a system with as little as 64 MB of physical memory and for running complex clients.
Table A-4 lists the recommended minimum quota values for non-VGA devices. These server quotas can set by defining global symbols in the file DECW$PRIVATE_SERVER_SETUP.COM. If the file does not exist, copy the file SYS$MANAGER:DECW$PRIVATE_SERVER_SETUP.TEMPLATE to SYS$COMMON:[SYSMGR]DECW$PRIVATE_SERVER_SETUP.COM, as described in Section 3.1.
| Quota | Value |
|---|---|
| DECW$SERVER_FILE_LIMIT | 400 |
| DECW$SERVER_ENQUEUE_LIMIT | 2000 |
| DECW$SERVER_WSDEF | 10240 |
| DECW$SERVER_WSQUOTA | 16384 |
Tuning for Animation Applications
If your application involves lengthy animation sequences of large models or assemblies, performance can be improved by setting the following server working set quotas and values as follows:
| Quota | Value |
|---|---|
| DECW$SERVER_WSDEF | 10240 |
| DECW$SERVER_WSQUOTA | 20480 |
These parameters should not be tuned upward unless you have at least 128 MB of physical memory. |
Tuning for Memory-Intensive Applications
If you are running one or more memory-intensive applications (such as the HP Secure Web Browser) on a system with a substantial amount of physical memory (512 MB or greater), performance can be optimized by setting the following server quotas and values:
| Quota | Value |
|---|---|
| DECW$SERVER_FILE_LIMIT | 6000 |
| DECW$SERVER_WSDEF | 32768 |
| DECW$SERVER_WSQUOTA | 65536 |
| DECW$SERVER_PAGE_FILE_QUOTA | 2000000 |
To determine whether you need to set larger parameters, monitor the server process during the heaviest display usage. If the working set use approaches the maximum values, then you need to adjust the value of the DECW$SERVER_WS* server parameters.
However, do not set large values unless it is necessary. If you set these values too high, performance may be degraded. Optimal DECwindows server performance depends on application demands and available physical memory.
The next time you restart the server, the new values will take effect. If, after initial tuning and considerable use, the server is failing or is unnecessarily unresponsive, the server may have run out of memory or memory may have become fragmented. A particularly demanding application may require that you give the server even larger DECW$SERVER_PAGE_FILE_QUOTA value. Note that pagefile quota for the server is derived from system page files.
If the server error log SYS$MANAGER:DECW$SERVER_0_ERROR.LOG contains the statement xxx: Out of memory, increase the pagefile quota for the server. Set this quota by modifying the DECW$SERVER_PAGE_FILE_QUOTA parameter in the file DECW$PRIVATE_SERVER_SETUP.COM. Note that in multihead configurations, the DECW$SERVER_PAGE_FILE_QUOTA parameter should be increased to meet your system requirements.
Table B-1 lists the DECwindows Motif keymap names. The table is arranged based on the language for which each keyboard is designed.
For information about changing the default keyboard layout, see Section 3.5.
