Obviously, performance depends on your system specs - but no matter your horsepower, you will still be able to bring any high-end system down to its knees, FlightGear is not particularly optimized and is generally a "resource hog", and there are a ton of factors that are having an impact here, including stuff contributed and developed by scenery and aircraft developers that may have significant effect on your frame rate and frame spacing. Usually, these things cannot be looked at in isolation - there are many features and factors that mutually affect each other. Aircraft like the 777-2000 or extra500 will remain heavy, no matter what is done on the FG side of things, short of procedurally optimizing textures, 3D models and bytecode...
And we're still missing the tools to really enable non-coders to easily identify expensive features (including scenery, aircraft, scripts etc), "expensive" in terms of CPU/GPU/RAM and VRAM utilization.
It is something that is being worked on, but it's probably going to take another ~2 release cycles until something materializes.
Please, just keep in mind that this is not generally a problem about FlightGear itself: some of us are actually working towards a more framework-centric development model, so that there's basically just a single component that can be optimized over time, while all aircraft would benefit from such optimizations automatically - unfortunately, this requires more coordination, organization and collaboration than most contributors are willing to put up with, because it no longer is just about a certain instrument and/or aircraft, but about generic development - so that good ideas end up being adopted in a poor way using copy&paste methods instead of generalization. Undoubtedly, there are some really cool aircraft, but many aircraft developers tend to use resources (textures, 3D models) and scripting constructs that are extremely heavy, and they're not really aware of the impact this is having on final FG performance.
