hi Dojo,
The default number of SLPort processes on a DMA is five but it is possible to influence this and specify less or more simultaneous SLPort processes as described in below documentation link
But in which situation would it be beneficial to deviate from the default? When would it be helpful or advised to specify less or more simultaneous SLport processes?
Context: I noticed the five SLPort processes on a particular DMA are running quite high in cpu load (average about 12% each) so I am wondering if changing this setting would be beneficial for the performance in any way or not.
Thanks a lot!
Koen.
Hi,
SLPort is still a 32-bit process, meaning that there's a memory limit around 4GB. In case this limit is reached, there will be a crash of that process hence why it's then beneficial to have more processes when this is the expected amount of memory and not a memory leak. This could be useful in a multi threaded timer polling environment where there are a lot threads present in SLPort.
In don't think that changing the setting would be beneficial for the CPU load in this case as an element is linked to a polling thread in an SLPort process, so the CPU that this thread uses will still be the same.
