This is great if your whole application is written in WebAssembly. However, most WebAssembly usage is part of a “hybrid application” which also contains JavaScript. We also want to simplify this use case. The web platform shouldn’t be split into “silos” that can’t interact with each other. Thankfully, WebAssembly Components also address this by supporting cross-language interoperability.
Under load, this creates GC pressure that can devastate throughput. The JavaScript engine spends significant time collecting short-lived objects instead of doing useful work. Latency becomes unpredictable as GC pauses interrupt request handling. I've seen SSR workloads where garbage collection accounts for a substantial portion (up to and beyond 50%) of total CPU time per request. That's time that could be spent actually rendering content.
