This is valid for both Mars and Neon.
In a large project using F3/Open declaration Eclipse hangs for several seconds before it is actually jumping to the declaration.
It can find pretty much everything so the index seem to be updated.

The first F3 always succeed but at the same time the cpu load goes way up, sometimes filling up more than one core. Until it drops the next F3 have to wait.
During this the Open Declaration is showed as waiting in the Progress window. Sometimes an EnclosingASTNameJob is lited as well.

This situation makes it pretty much impossible to work with.

Any suggestions on resolution are most welcome.

My index cache setting are:
Limit relative to the maximum heap size: 50%
Absolute limit: 4000M

eclipse.ini :
-startup
plugins/org.eclipse.equinox.launcher_1.3.200.v20160318-1642.jar

Go to "Window -> Preferences -> General -> C/C++ -> Code analysis" and disable "Syntax and Semantics Errors -> Abstract class cannot be instantiated"
