for install size, it depends on your architecture, we use wasmtime under the hood so a lot of the size is related to that: https://wasmtime.dev/

You can also take a look at our binary releases to get an idea: https://github.com/extism/extism/releases/tag/v0.1.0

In terms of memory usage, as the host you can constrain the memory that your plugin can use. There is a minimum of one Wasm page (64KB in this case).
