I am transitioning from CW 9 to Xcode and currently have 2GB in my
dual 2.5 GHz G5. What kind of speed ups should I expect for compiles
and debugging if I were to invest into an additional 2 GB?
Did you try having a look at your whether your system has to swap to
disk or not during compiling and especially linking? Top or Activity
monitor can give you some insight.
I know
those things cannot be quantified exactly because it will depend on
the size of the project, etc., but my guess is some kind of generic
assessment of whether benefits can be expected to be minimal,
notable, or pronounced should be possible (perhaps based on own
experiences).
How large are your resulting binaries? Xcode/gcc blows up my debug
build to ~600MB size total (dylibs plus main executable), and linking
or debugging it causes my PowerBook with 1.25GB RAM to swap - after
all, the program itself needs to deal with datasets of 1GB or more. A
fully optimized Release build takes about 20 minutes to link due to
constant swapping (dead code stripping requires -gfull, resulting in
insanely large binaries).
