I'm running a streaming aggregator and am looking for ways to lessen the burden on my backend. Would moving some processing tasks to clients using WebAssembly really make a difference, or would the impact be minimal?

Absolutely! WebAssembly is a game changer. It shifts computational tasks like video processing and decryption from the server to the user's device. This way, your backend doesn't have to handle every stream, turning it into a simple data distributor. This drastically cuts down your CPU usage and allows for better scalability with fewer resources.
WASM can help, but perhaps not in the way you'd expect. It can take care of tasks like parsing, transforming data, or some light processing, but don’t forget that most streaming issues are actually related to bandwidth and I/O rather than CPU usage. So, while it can reduce some load, it’s not a cure-all for backend stress.
It really depends on where your backend is struggling. Have you done any profiling to pinpoint the bottlenecks? Are you dealing more with issues like too many socket connections or heavy CPU usage from transcoding?
