Have you ruled out local wireless issues, such as a literal side-by-side test? Does the problem still exist when wired? ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP ----- Original Message ----- From: "Mark Tinka" <mark.tinka@seacom.com> To: "Matt Hoppes" <mattlists@rivervalleyinternet.net> Cc: "NANOG" <nanog@nanog.org> Sent: Thursday, October 29, 2020 7:31:59 AM Subject: Re: Apple Catalina Appears to Introduce Massive Jitter On 10/29/20 14:27, Matt Hoppes wrote:
Is it actually jitter or is it potentially the wireless network card going into sleep mode? I have seen that type of behavior on Apple products when the cards go into low power mode although I can’t say I have noticed that on my laptop.
Not, not sleep mode, because I am actively using the device to move data to/from the Internet. I was actually struggling to upload some files to Youtube last weekend, and had to use another computer to do it as I couldn't figure out what was going on. That it is how bad the jitter is. It seems to be a much bigger problem for the upload direction than the download, but it, inevitably creates a symmetrical performance problem. Mark.
