I have a pretty fast Mac, running Windows 10 in a VM. I have been getting tired that Edge loads a little slowly - like 5 seconds to bring up a Google home page screen. It's instantaneous on the Mac side, and if I hit refresh in Edge once it opens up and loads, Google refreshes instantaneously there too. I have tried all the tricks - performance tweaks in Windows 10, turn off all the visual candy, no extensions, clear cache, network conditioning at 100% in Parallels, let it run after its closed, you name it. But I finally found an obscure site that mentioned one thing that I did not see anywhere - I tried it, and boom! Edge (the latest Chromium one) comes up INSTANTANEOUSLY! I even turned back on "Let window manage.." for the display eye candy, and loosened some other things I turned off, and it still pops right up! I wanted to post it here in case it helps others. Open Windows Start > Settings > Network & Internet > Proxy. Toggle off "Automatically detect settings and Use a proxy server." Scroll down, click Save.
See https://forum.parallels.com/threads...ter-on-mac-os-so-slow-using-parallels.344397/ Confirming that this is the problem and is a Parallels reproducible bug. It is insidious in the latest version of Parallels 20.2.0, build 55872, in that Resource usage changes after windows ot the mac goes to sleep, even if configure is locked! Sequoia 15.2 (24C101), Macbook Pro M3, Windows 11 ARM, all fully updated. Workaround 1. Always shutdown Windows before letting mac go to sleep. Workaround 2. Run MS Edge at VM boot, the ookla. If slow, open configure, then set Optimization to No limit and reboot. So far, the two workarounds 1 and/or 2 have worked most if not all of the time, although I have rebooted the Mac and VM so much just to be able to work, I can't vouch that this works with it works in all situations. It has helped to always perform Workaound 2 before doing any work.
