I haven’t experienced this with Fleet after using it some months.
However, from using the other JetBrains tools the performance killer for builds and indexing libraries and documentation has typically been slow file system access.
These IDE even warn you when they detect this. I don’t remember seeing this warning in the Fleet preview.
A common solution is to disable aggressive anti-virus scanning for you project folder and some key application folders so it does not slow down the build.
Another cause is slow remote mounted file systems that you might have if you are using VMs, WSL or Docker.
If I remember correctly the docs have detailed information about this.
