I'm not sure what you mean.
When you press 'install' in the package editor, the following happens:
- The IDE calls 'make IDE OPT=-Cn' to compile the IDE (not the
LCL, not any component) without final linking. This is needed for
packages using the IDE sources directly. FPC will only recompile what
has changed.
- IDE compiles all changed packages
- IDE links the new IDE
- IDE restarts

Every step requires some checks. And the first time the OS has to load
a lot of files into its cache, so it can take a lot of time the first
time. After that the IDE rebuilds itself in a few seconds on a recent
The first step could be omitted when the IDEIntf is good enough. We
could ask on the mailing list if this is already the case. Maybe this
halves the time needed for building.
