Very good. I didn&#x27;t benchmark it myself, but the language is designed for high-performance computing, and the authors&#x27; PLDI paper [1] shows it is competitive. Given that at the lowest levels, Terra basically reimplements C, and both compile to LLVM IR, similar performance is unsurprising to me.<p>The main point that gives Terra an edge is that its macro system makes implementing and testing potential optimisations easier.<p>[1]: <a href="http:&#x2F;&#x2F;terralang.org&#x2F;pldi071-devito.pdf" rel="nofollow">http:&#x2F;&#x2F;terralang.org&#x2F;pldi071-devito.pdf</a> § 6.
