--- Comment #6 from tasnim <tasnimrock2k6 at gmail.com> ---
We got help from v8 engineer who reported compiled wasm size of ~198MB for the wasm (https://readalong.google.com/wasm/wasm/simd/481866636_7/wasm_wrapper_release_simd.wasm) on arm architecture. Is there a way to do the same for webkit?

On my mac, if I start the web app on chrome, chrome's taskmanager (can be opened up via settings -> more tools -> taskmanager): reports ~500MB (refer attached chrome_memory). Safari on Mac via activity monitor for the same reports to be ~2GB (refer attached safari_memory).

Sorry, I wasn't able to clearly infer chrome tab's memory via activity manager. Any pointers on what more we can do to investigate memory usage on safari?
