Performance and Features review on SonarLint with Visual Studio 2019 and SonarQube

I am considering integrating SonarLint within Visual Studio 2019+ and SonarQube, and looking for a report of its performance and features for questions like below:

Q1 Will SonarLint slow down VS when connecting to SonarQube?
Q2 What additional features will it get by connecting to SonarQube?

(1) SLVS fetches information from SonarQube/SonarCloud when a bound solution is opened, and then periodically checks for updates in the background (fairly infrequently - currently it polls every ten minutes if I remember correctly, although this will change to use a push mechanism in the mid-term).
Apart from that there is no communication between the IDE and server, so there should no observable impact on performance.

Having said that, there is a known issue where SLVS can cause a gold bar to appear when opening a large bound solution in VS. We’re aiming to fix that in the next release, which should be within the next couple of weeks.

(2) there is some information in the SonarQube docs and more detailed information in the SonarLint wiki.
