So far, the LLVM was built as optimized for size what made the wasmer codegen much slower: ``` time target/release/wasmer run -l --disable-cache php/php-32 --compiler-threads=12 -- --version real 0m33.667s user 5m31.292s ``` After the change we get to the following numbers: ``` real 0m16.950s user 3m16.750s ``` The binary size impact for wasmer CLI binary is about +20%.

I find +20% size for -50% compile time to be a good tradeoff. |
