Adjusting the project file to ahead-of-time (AOT) compile and include SIMD support. Fixing a publishing error if you accidentally checked the AOT compile option in the Publish dialog. WebAssembly has a feature called fixed-width SIMD that takes advantage of hardware instructions to speed up calculations by running them in parallel. Chrome and Firefox added support for the feature back in 2021, which was good, but many devices couldn’t leverage the performance improvements without Safari’s support. That all changed on March 27th, 2023, because Safari 16.4 was released, and now all modern browsers support WebAssembly fixed-width SIMD! Fixed-Width SIMD (Single Instruction, Multiple data) is a type of parallel processing that takes advantage of an architecture’s SIMD instructions to perform the same operation on multiple data points simultaneously. Because there are multiple types of SIMD, the WebAssembly Community Group decided that it would be best to start with fixed-width 128-bit operations because they’re available across most modern architectures and are proven to be performant.
