What is your anti-virus software?

I dumped Norton, then added " Security Suite" from Spectrum. Didn't realize antivirus would slow down outgoing files. I will try to test this. Thank you

I shut the antivirus down but no change regarding speed of sending an e-mail with an attachment.

Does that also happen in Troubleshoot mode?

Not sure if Spectrum is any better.

The only reliable way to shut down anti-virus software is to start Windows in safe mode. Try to start Windows 11 in safe mode with networking enabled.

Does the problem go away?

Windows safe mode disables anti-virus software. This is a troubleshooting step, not a solution. Note, you'd need a wired connection for this, as WiFi will not work in Windows safe mode.
