J-Link RTT Viewer output is very slow with latest tools

[sbutler]

I just upgraded to JLink_Windows_V635g.exe and the latest "V640".

The new version are causing the J-Link RTT Viewer to update the log terminal very slow.

Is there a workaround? or do I need to downgrade?

Isn't this a question you're more likely to get an answer to in the Segger forums as they make the product than the Nordic ones as Nordic is just a customer?
