Susie201110141, for me, I have a WSL2 Ubuntu 20.04 distro running. I also have Docker Desktop, which uses that Ubuntu distro for me to run containers. I have 3 VMs I use all the time. One runs Server 2019 with SQL Server 2012 Std, And then a couple of Windows 10 2004 machines. One runs legacy applications written in MS Access, and the other one is a VisualStudio 2019 development environment.
The thing is, the poor performance is noticeable even before opening the apps, simple things like opening a Windows Explorer window, double-clicking on a folder to open it. Sometimes the actions are delayed, menus take a few seconds to come up.
Prior to running the 15.5.5 update, I ran my VMWare setup with the "Allow some memory to be swapped". After the update, that became impossible, to the point of machines pretty much freezing. So I turned to "use all available memory up to X". And it ran a "bit" better, but not with WSL2 distro running. My poor old Alienware 15 R3 is on full fan on all the time now, and that was not the case prior.
I have already done much work moving from using a vm for my linux development to use WSL2 because of the versatility, but if I can't figure out a way to get the performance going things are going to look like a painful downgrade (pre-15.5.5, back to WSL1) will be in order.
I hope this is helpful.
