Summary: Local testing has demonstrated a great speed improvement, compare the following: 1) Existing version: ``` $ time llvm-cov show -format=html -output-dir=report -instr-profile=... ... The tool has been launched: 00:00:00 Loading coverage data: 00:00:00 Get unique source files: 00:00:33 Creating an index out of the source files: 00:00:34 Going into prepareFileReports: 00:00:34 Going to emit summary information for each file: 00:28:55 <-- 28:21 min! Going to emit links to files with no function: 00:28:55 Launching 32 threads for generating HTML files: 00:28:55 real 37m43.651s user 112m5.540s sys 7m39.872s ``` 2) Multi-threaded version with 32 CPUs: ``` $ time llvm-cov show -format=html -output-dir=report -instr-profile=... ...
