With W10, my 4 Gb laptop suddenly crawled to halt (probably after an update). I noticed memory usage had peaked at 85% and the disk was getting hammered, so obviously it had started swapping furiously. I added another 4 Gb and it’s is now usually OK. Only if windows updates itself the subsequent disk traffic caused stuff to go slowly. For 10 minutes or so after starting the machine.

4G is a good amount of memory for W7.  For W10, its barely enough.  I have 16g Win10 machines.  One of them may have 32G.  I’ve never tried more than one instance of WSJTx though.  I usually have Outlook, Excel, Word, Chrome and three instances of Putty open while WSJTX decodes.

Hi Bill,

 

Both of them have 4Gb. One is Win7 the other Win10.

 

I did another test today with 3 instances on the Win10 machine and the processor utilization never went over 60%, but it still stopped decoding.

 

Cheers,

Peter

Hi Peter,

how much physical memory does your PC have?
