High Priority for WSJT-x in Slice Master

Greg, N6GDGreg, N6GD Member
First, thanks for all your advice and quick replies!!  You're the best!

As your reward, you get another question!:

Can we set up Slice Master to run WSJT-x (or CW Skimmer) with High CPU priority?

My computer bogs down when I run three copies of WSJT-x at a time, and it bogs down even more when I run even one copy CW Skimmer on top of those!  WSJT-x will drop packets and cease to output any information when it gets bogged down.  The cure for me is to change the CPU priority to High for each copy of wsjtx.exe and for each copy of jt9.exe using Task Manager  (in the Processes tab, right click on the process listing, choose "Set Priority", choose "High").  I have to do this every time I fire up a new copy of WSJT-x.

Is there a way to get Slice Master to do this for us automatically?

This command will launch WSJT-x with High priority from a cmd window:

      >  cmd /c start "" /High "C:WSJTwsjtxinwsjtx.exe"

I tried inserting this entire string into config.ini in the exe_path, but that didn't work.
I also tried creating a shortcut with this command line and inserting the path name for the shortcut into exe_path, but that didn't work either.

I am running under Windows 7 in Parallels on a MacBook Pro 2012.

Any suggestions?

In advance, thanks!!!

    I would drop Don, K1DBO a note. He is extremely responsive.

    Not sure how many cores you have allocated to the Windows VM, but you could "steal" some more cores from your Mac to give your VM some extra help.

    Yes, that command works from a command line. Is there a way to insert that into config.ini to assign high priority every time that Slice Master fires off a copy of WSJT-x?

    I sent Don a note.  I'll let you all know what replies I get.
