Visual Studio for Mac is using high CPU and slow

I have a 2017 iMAC Pro (Bought 2019):

3.2 GHz 8-Core Intel Xeon W

Radeon Pro Vega 56 8 GB

32 GB 2666 MHz DDR4 ECC

2TB SSD Hard drive

I have Visual Studio 2022 and also Visual Studio 2022 Preview (To test if the none preview is buggy) and both are slow, using sometimes up to 200% of CPU and 12GB of RAM in Activity Monitor.

I have reinstalled MAC OS Ventura 2 times and reinstalled VS for Mac so many times, cleared cache etc...

The editor when editing either a .razor or razor.cs file keeps hanging. As an example, as I press a key on the keyborad, it sometimes can take 1 second to display 1 key pressed. So if I press 10 keys on the keyboard, I have to wait and watch the keys being pressed in the editor over 10 to 15 seconds.

I purchased CleanMyMac and did things like Clear RAM, run Maintenance scripts and clear cache files but nothing happens.

The only thing I can do is restart my iMac Pro and have normal use for a few minutes until it becomes unusable again.

I have disabled all extensions except debug.

I am developing a Blazor Server App ASPNET Core 7.0, no mobile development.

All other apps on my iMac work super fast and no issues, only Visual Studio for Mac. (Even when I close all other apps).

I have searched numerous posts over the last 3 years WHY its happening, I have done everything to try and resolve this issue making sure I have all the latest update, disabled extentions etc.... but nothing works.

How can I solve this issue?

Regards

    its always using so many CPU resources, even on idle, when I took a sample with mac activity monitor on the high load vs process, I saw many threads calling DispatchCallSimple and MethodDescCallSite::CallTargetWorker recursively in libcoreclr.dylib with a deep call stack, it's really annoying!

    Hello @James Horrocks ,

    Thank you for taking time to post this issue in Microsoft Q&A forum.

    If you are using the latest version of Visual Studio for Mac and you can confirm that there aren't any other applications/processes which make VS for Mac slow, then, in case it’s a potential issue, please kindly submit a ticket on our Developer Community and attach the related system log file for further investigate.

    Thanks for your understanding, have a nice day.

    Sincerely,

    Tianyu
