Many thanks Mike, With that .json file Rx CPU is now 8-10%; Tx CPU now 7-8%
FYI: Over last several days, there have been two rc2 crashes; but I've not had time to investigate. The reduced CPU load may eliminate the crashes (will know in a few days). 73, Roger (K7GXB) -----Original Message----- From: Black Michael <mdblac...@yahoo.com> Sent: Wednesday, July 12, 2023 06:17 To: 'WSJT software development' <wsjt-devel@lists.sourceforge.net>; Roger Newey (K7GXB) <k7...@narundi.net> Subject: Re: [wsjt-devel] High CPU load with 2.7.0-rc2 Save this into a file called "hamlib_settings.json" and place in the same folder as WSJT-X.ini Should improve things until I get this fixed. { "config": { "async": "0" } } Mike W9MDB === _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
