the answer is stuff your machine with as much RAM as possible, but
then that's always the answer.
That's not a reasonable answer. A glorified text editor should not
require a gigabyte of ram. As computers have gotten faster, computer
programs have required more ram and faster processors. The source
code is no more difficult to edit than it was a decade ago. Writing
text should be a solved problem.
Just wanted to reiterate since people keep giving these sweeping
generalizations about Xcode memory requirements...
The editor part of Xcode 2.x ran quite acceptably on my 450Mhz G4
tower with 1GB of RAM. Not extra-snappy but well enough to be quite
productive. What really kills performance is a RAM starved machine
when doing builds. The GCC tools, particularly the compiler are
massive memory hogs and will eat up 2GB of RAM doing slightly non-
trivial compiles. They could take up more depending on what you are
building. If you don't have at least that much RAM, the OS will page
to disk which will kill your performance by at least 100x. Xcode the
application can't do much about that since it's just launching
processes for the various GCC tools. So, the RAM is going towards
builds not the Xcode application itself. Check System Profiler and see
where your performance problems are. See which processes are using how
much CPU cycles and RAM and if they causing paging to disk.
While we could complain about GCC being a pig, I don't think it's that
wrong to expect a developer to have an extra $50 worth of RAM in a
machine that costs $1000-$2000.
