Linux Compiler Benchmarks Of LLVM Clang 3.5 vs. LLVM Clang 3.6-rc1
Written by Michael Larabel in Software on 25 January 2015. Page 3 of 3. 3 Comments

Compile times were a little slower under Clang 3.6 than Clang 3.5, but we'll see how things pan out by the final release next month.

There was some fluctuation in other C/C++ benchmarks, but it's difficult to call anything definitively due to the margins and only testing from this single Xeon Haswell system.

MP3 encoding was close but leaning slightly in favor of Clang 3.6

HINT and Apache ended out my round of weekend Clang benchmarks by showing some nice performance improvements over Clang 3.5. The raw results in full can be analyzed via this result file. As the LLVM/Clang 3.6 release approaches toward the end of February, I'll be back with more compiler benchmarks across a range of Linux systems.
