I was excited to read this post because I haven't yet tried WasmGC for anything beyond tiny toy examples, but was disappointed to find no actual numbers for performance. I don't know the author well enough to be able to assess their assertions that various things are "slow" without data.
This was a quickie post for me. Just a tale of what my experience has been. No in-depth, apples to apples comparison so I don't know the magnitude of the performance differential.
