Increase default number of processing threads

[David10]

We're trying to update the default number of processing threads on the Alteryx Server in Engine Configuration, but it won’t allow us to increase beyond 10.  Has anyone encountered this issue and know of a resolution?

Thanks

@David10 The ui spinner in system settings is limited to values 0-10. In most cases this should be sufficient for your hardware. Please keep in mind that this value is set to a default based on your hardware at first run/setup and typically this value shouldn't be changed. The only appropriate reason to change the value is if the hardware is changed to add or subtract logical processors. In that case you should set the value to the number of logical processors + 1 or 10 which ever is smaller. For example if your machine has 4 physical cores and is single threaded it would have 4 logical CPU's and the value should be set to 5. If it has 4 physical cores and hyper threading is enabled it would have 8 logical CPU's and should be set to 9.

As an additional note it is possible to set values larger than 10 in the settings file directly, and if a CPU with more than 10 logical processors is detected during initial setup this value will be set appropriately for that CPU (i.e. 16 logical CPU's would get a value of 17 and 32 would get a value of 33 etc...). However, attempting to change the value through system settings will set the value to 10 as a maximum.

Thanks Kevin. I was able to increase the Default Number of Processing Threads using RunTimeSettings.xml.
