Thanks.
We’re aware of a performance issue with our Javascript/Typescript analysis that happened a little bit before June 20th.
We’re aware of an issue affecting our Javascript/Typescript analyzer that you can learn about here (as well as a workaround).
In principle, using the property sonar.typescript.tsconfigPath to point to the tsconfig.json in the project root should solve the issue.
And, a better fix should be deployed to SonarCloud soon.
Can you give this a try to see if the performance improves and the impact on memory is lighter?
