SDRuno 1.1 Horrendously Slow

Postby chimbo1984 » Tue Nov 15, 2016 1:43 am

I just upgraded to SDRuno 1.1 and its practically useless to me. The performance has degraded terribly and I am not able to use the application in any meaningful sense. For info, I have an eight core CPU running at 4.2ghz, 16gb of ram, and a high performance GPU and plenty of disk space yet SDRuno is using ~25% of my CPU. No way should the software be using this much computing capacity.

In using the application, there is a five to eight second lag in everything I do. But outside of SDRuno, Windows 10 is performing just fine.

Any suggestions? What is the potential for a quick fix for this issue?

That doesn't sound right. I have a worse machine than that and I typically get 3-4% cpu usage with a 2MHz bandwidth and that goes up to about 15% if I select a 10MHz bandwidth.

If you send us an email at I'm happy to arrange to log in remotely to see why it could be running so poorly.

Best regards,
