Just a quick question... my TiBook 550 / 256, OS X 10.2, is proving

unacceptably slow building AU with ProjectBuilder, and feels very

general (compared to the same machine running Classic and building VST
plugins [yes, I know VST is simpler than AU],
APIs aside, I'm also guessing that you're comparing building VST with
CW
and building AU with PB. I think that the bigger issue is the
compiler.
PB (or more specifically, gcc) builds WAAAY more slowly than CW. I
love a
lot of things about PB and gcc, but definitely my big gripe (and I'm
certainly not alone) is speed of compiling.
Yes, it's a problem of gcc (or jam ?), especially when you are building
C++ files. For plain C it's much faster and for Objective-C it's fast
enough, I think. I don't know what Apple did with the gcc, but on the
old Mac OS X Server 1.x is was about 12 times faster (as it is on other
operating systems). Anyway, to speed up the compiler, I'd highly
recommend to use precompiled header files. With our Carbon projects
compiling takes half of the time since we are using this, though it is
still about 5 to 10 times slower than the same project compiled with
CodeWarrior.
IMO Apple should fix this asap, compiling mid size projects is not fun
at the moment.
Anyone working with a machine of this sort of spec? I'm wondering if
an
extra 256M ram is going to make all the difference or whether I should
start saving up for a new Powerbook (or even a Dual G4 desktop)
already :-(
Does it have 256 now? Mac OS X likes to use a lot of memory, and I
used
to use it with only 256 MB of RAM. When I upgraded to 512 MB, I felt a
big difference. :) So I would recommend at least 512 MB...
Right, 512 MB is the recommend minimum. A dual processor would not help
much; as far as I know ggc is using only one at a time (though you'd
have a faster processor, a faster harddrive, faster RAM and the PB GUI
stuff could be done by the second processor, of course).
