It's probably PR12517. Looking at the clang binary, it's got a /home/ dir in RPATH: $ objdump -p clang+llvm-3.3rc3-Ubuntu-12.04.2-x86_64/bin/clang | grep RPATH RPATH $ORIGIN/../lib:/home/aadgrand/tmp/LLVM-3.3rc3/rc3/Phase3/Release+Asserts/llvmCore-3.3-rc3.obj/Release+Asserts/bin This will slow things down if the system tries to automount /home/aadgrand. Maybe we should merge r182559 to the release branch? Or at least we should take care not to build it in a /home directory. - Hans On T...

Hi Bill, I was running some benchmarks and was surprised that the startup performance of your binaries is much worse than the stable binaries for 3.2 I've used: http://llvm.org/releases/3.2/clang+llvm-3.2-x86_64-linux-ubuntu-12.04.tar.gz vs http://llvm.org/pre-releases/3.3/rc3/clang+llvm-3.3rc3-Ubuntu-12.04.2-x86_64.tar.gz On a simple hello.c file: /ssd/bench$ TIMEFORMAT="%E"

Hi LLVM-ites! We are doing a quick test of 3.3rc3. Our testers did a quick turn around and created binaries which you can test. Please give them a go and let us know how they work for you. They are here: http://llvm.org/pre-releases/3.3/rc3 We don't have a lot of time remaining in the release cycle, so please do whatever you can to make sure they are solid. In particular, make sure that
