I'm still getting used to Xcode, so maybe this is a known issue with a
workaround. When editing code, it's *extremely* sluggish on my G5. To
the point where deleting or adding a single character can take up to a
full second. It's almost like my machine is swapping like mad, but
according to top, that's not the case. I thought it might be my use of
multiple fonts, but reverting back to a single font didn't help the
situation.
Xcode and performance are not necessarily good companions as far as I
can tell...
I've had the same symptoms you've given above in the following
situations:
1) Code completion on a G4, especially with < 1GHz clock frequency is
unbearable slow.
2) Predictive compilation also has a tendency of slowing down the
editor.
3) Don't leave the debugger window open while you're editing code. The
longer the window remains open while you're editing, the slower the
editor gets.
4) Don't leave the header portion of a framework open in the Groups &
Files pane while you're editing. This is a quite interesting
performance problem because it does not appear immediately. I.e. if
you're making the headers of the AppKit framework visible in the Groups
& Files pane and leave it open while you're editing, then the editor
will get slower and slower over time. In the first few seconds you
won't notice any slow down, but after 20 minutes or more Xcode can
easily take 5 seconds to react to a key press on a 450MHz G4.
5) Editing files with more than a few thousands lines of code is, well,
really slow. I.e. open the QuickTime/Movies.h header file in Xcode and
watch the editor go down on its knees while its trying to layout /
syntax highlighting the code.
