I am involved with a very large, complicated build process for the
Corona SDK that was building on a Mac Mini, I think Core Duo 1.83Ghz
with 1GB of RAM.
Under Xcode 3, the build times were about 1 hour. We moved to Xcode 4
and moved to clang/llvm and saw our build times drop to about 35
minutes. (We build Android stuff too in this so we Xcode 4 can't
speed up those parts for us.)
We just upgraded to a faster Mac Mini (2.4GHz Core 2 Duo with 4GB of
RAM) and our build times are now 20 minutes.
We just started running nightly automated builds with automated iOS
(and Android) on-device tests. To pull this off for iOS, we use
Scripting Bridge with Xcode. Unfortunately, Xcode 4 is currently
terribly broken with Scripting Bridge and totally unusable for us in
this aspect and we had to install Xcode 3.2.6 to pull this off. I
would estimate that Xcode 4 is twice as fast at building for us.
So thank you Xcode 4 team for the tremendous performance boost with
clang/llvm! (But please, please fix Scripting Bridge and come up with
better ways to automate iOS device builds and runs.)
Thanks,
Eric
