Re: DXLabs and CW Skimmer - DXLabs is sluggish to Non-Responsive

Kent Olsen


This is the same issue I reported:

I was never able to find a resolution. 

I just tried to start my computer in safe mode with networking. The problem is CWSkimmer will not start via SliceMaster like this.

I have an issue with DXLabs when running CW Skimmer, where DXLabs programs slow to a crawl or halt when CW Skimmer is running (e.g., program startup from launcher, or communication from WW to Keeper to look up callsign information, to name a couple of examples).  Once I close CW Skimmer DXLabs immediately takes off.

The setup is a Windows 10 machine (current on maintenance), running on an HP i5 PC with 16GB.  Running a Flex 6600, Smart SDR (V3, but V2 had the same issue).  The PC runs at 50% busy or less with similar memory utilization.  I've even gone so far as to lower the task priority of CW Skimmer to make sure its primary thread is not monopolizing a core above a DXLab task.  I've also done the opposite with DXLabs tasks to raise their priority.  None of this changes a thing.  While CW Skimmer is running DXLabs is usually slow to non-responsive.  Once CW Skimmer is ended, then DXLabs runs just fine.  Also I find no other program running concurrently in the mix is exhibiting this characteristic sluggish behavior.

Like I said, it seems to be related to the inter-task communication method used by DXLabs, but I can't put my finger on it.

I'm in no way inferring any sort of defect in DXLabs.  The issue is likely on my side but I can't seem to put my finger on it and would appreciate any insight.

+ Please reboot Windows into "Safe Mode with Networking". Then start your DXLab applications and CW Skimmer, noting that Commander will be unable to communicate with your transceiver via a serial port in this configuration (serial port drivers aren't loaded when Windows is booted into "Safe Mode with Networking"). Do you still experience the slowdown reported above?
