Description

Do Find All References on some "big" search like std::move and then Cancel in the "confirming" phase. I'm seeing the partial results take a lot longer to appear on Linux than on Windows by a factor or 4, i.e. many seconds more.

I'm not sure if there are other performance issues on Linux or if it's isolated to this particular example.

Research direction

Reproduce Find All References for a large search such as std::move on Linux and Windows, then cancel during the confirming phase. Compare how long partial results take to appear and investigate whether the slowdown is specific to this case or reflects broader Linux performance issues.
