Only gave a single example below, but did run a sampling of benchmarks and the results look to be correct now.

Notably the docs for running WASM benchmarks is very out of date right now: https://github.com/dotnet/performance/blob/main/docs/benchmarking-workflow-dotnet-runtime.md#dotnet-runtime-testing-for-wasm, I ended up getting it working but having up to date guidance would be great.
-- Most notably test-main.js was moved, tests won't run since it can't find the 9.0.0-dev packages, and test-main.js was updated to require --module

Only gave a single example below, but did run a sampling of benchmarks and the results look to be correct now.
Notably the docs for running WASM benchmarks is very out of date right now: https://github.com/dotnet/performance/blob/main/docs/benchmarking-workflow-dotnet-runtime.md#dotnet-runtime-testing-for-wasm, I ended up getting it working but having up to date guidance would be great.

-- Most notably test-main.js was moved, tests won't run since it can't find the 9.0.0-dev packages, and test-main.js was updated to require --module

@tannergooding thanks for getting this done so quickly, the initial data from our benchmarks also indicate there now a net improvement in here. Excellent work.

Only gave a single example below, but did run a sampling of benchmarks and the results look to be correct now.
Notably the docs for running WASM benchmarks is very out of date right now: https://github.com/dotnet/performance/blob/main/docs/benchmarking-workflow-dotnet-runtime.md#dotnet-runtime-testing-for-wasm, I ended up getting it working but having up to date guidance would be great.

-- Most notably test-main.js was moved, tests won't run since it can't find the 9.0.0-dev packages, and test-main.js was updated to require --module

The MOV_VT numbers are very promising! Thanks for chasing this down.
