Lightly toasted, lightly seasoned, mostly correct.
Summary
The article discusses TPDE-LLVM, an open-source project that claims to achieve 10-20x faster LLVM -O0 back-end performance for code generation. This development responds to a 5-year-old comment by @nikic who stated that LLVM would need a 10x improvement to be considered "fast again" rather than just a 10% improvement. The project appears to be a significant performance enhancement for LLVM's baseline compilation.

· 3 pulledI can't say a 10% improvement is making LLVM fast again, we would need a 10x improvement for it to deserve that label.
