It looks like the DevOps pipeline is using the default -O2 optimization for Emscripten, which is why you’re seeing that in the build logs. To switch to -O3, you’ll need to pass it explicitly to the emcc compiler. Depending on how your pipeline is set up, this usually means adding -O3 in the Blazor WebAssembly AOT compilation settings or in the MSBuild arguments for the pipeline task. Basically, you want to override the default optimization level so Emscripten knows to use more aggressive optimizations. It might take a little trial to get the exact spot where the flag needs to be inserted, but that’s the general approach.
