eXodusFrequently Asked Questions
How do I Maximize eXodus’ Performance?
If you feel you are experiencing performance problems, there are three areas you may want to check: the characteristics of the X server (eXodus), the X client and host system, and the network configuration. Improper configuration of these areas can drastically impact the performance of the entire system.
Check the following areas for enhanced performance:
-
eXodus performance is directly attributed to CPU and network performance.
-
Optimize eXodus’ speed by the following configuration options:
-
Avoiding using Exact Match for the color matching tolerance in the screen definition (set using the Screen Editor command in the Settings menu).
-
Adjusting the screen refresh interval.
-
Mac OS 8/9) Increasing the preferred amount of application memory by clicking once on the eXodus icon and clicking File | Get Info (or by typing Command-I). Enter the new application size in the Preferred Size text field.
-
Using the local window manager instead of a remote one.
-
Trying a different Backing Store setting.
-
Disable unnecessary extensions by choosing the X Extensions icon from the Server Settings window.
-
Reduce screen depth <= monitor setting.
-
Avoid font servers.
-
Adjusting aspects of the network transport being used.
-
Check for other applications that share CPU time with eXodus. For example, print spoolers, program compilers, and backup utilities running in the background may cause eXodus (or any other Macintosh application) to run slower.
-
If eXodus appears to be running slower than expected, experiment with running the same clients over the same network to another X display server workstation or X terminal. It is important that these comparisons are treated equally. Platform characteristics should be similar, for example, CPU speeds, color versus black and white, etc. All other variables, such as network connections and traffic loads, should also be kept as similar as possible.
-
If a server is designed optimally to handle ten client connections at a time, its performance will suffer when it is overloaded with fifteen to twenty connections. The client applications’ performance will slow noticeably when the display server is handling many clients at one time (actually host usage and network traffic also come into play in this situation).
-
If clients are running slowly on eXodus, determine how much traffic is on the network and experiment with other networking connections. Since eXodus can be connected to multiple networks, make comparisons by running the same clients over different network connections. Remember to keep all other variables as equal as possible to ensure that only the network connections are being compared.
-
The speed and capacity of the network's physical transmission medium, along with the protocols, will also affect network performance. For example, Ethernet networks are faster than LocalTalk.
-
Check the number of programs running on the host. On some host computer systems, a large number of other clients running simultaneously can impact performance. Another consideration is the type of programs which are run at the same time as the X client. Usually, hosts can manage many interactive programs simultaneously without performance problems. However, if several CPU-intensive programs are run at the same time, system operations may slow down. In a similar fashion, the number of users on a system at any time will also have an effect on performance. If a given client is noticeably slow, try running it at a time when the system is not being used as much. If possible, experiment with running the client on another host computer system that is faster or at least has fewer users and/or processes on it.
