The Passmark score and how it relates to running SSDR.
Al / NN4ZZ -- 18-Jan-2015 -- updated notes based on user feedback
Some Flex users have reported issues with performance when running SSDR software. The symptoms are slow response, jerky screen displays, disconnects, etc. There are a number of potential reasons.
- Network or connectivity issues.
- Software, or driver issues. Malware.
- Inadequate PC performance
Passmark can help rule out your PCs performance as a factor. It can also be used to measure the impact of improvements. Based on the data collected, some Passmark performance metrics are more important as it relates to running SSDR and others are not. For example:
More Important -- 2D graphics score, Overall score, CPU score
Not as important – 3D graphics score and disk drive performance (although these do factor into the overall score)
The Passmark values here were compiled based on member feedback. The suggested numbers are based on SSDR running concurrently with other programs (browsers, email, loggers, fldigi, ddutil, etc). The data provided by the majority of members meet or exceed these numbers.
A Free 30 day trial of the Passmark tool is available to test your PC.
Notes & Caveats:
- Higher numbers are better, but these values below appear to be adequate with some headroom
- you may find that adding a good video card is all that is needed to bring your numbers up on an older PC.
- The recommendation does not take the network connection into consideration. A connection of 100 MB seems to be more than adequate. Wifi appears to be sufficient although some latency issues have been reported. This could change when the LAN remote and WAN remote versions are released
- The 3D graphics metric doesn’t have an effect on SSDR performance for the current design of the software but that may change some day.
- If you are running SSDR on a Mac in a virtual environment you may not get the 2D graphics performance as reported by Passmark.
- your mileage may vary based on how you use SSDR, other types of programs your run that may require more resource, your memory and disk setup, number of monitors, etc. If you have additional input on the Passmark numbers please post your results and comments to the forum. The numbers will be adjusted as needed.
