Creating a Model from a ModelRepr seems slow. Possible causes:

Lot of thunks / lazy vals during building the model
- Can we avoid some laziness at all?
Specifically: synchronization/locking in lazy vals
- Do we really need thread safety for these?
Lot of maps for resolving Refs
Model representation is deeply nested
- Can we represent, e.g. products with Maps instead of HCons?
???

We should also take a look at the serialized size of models, whether they should be optimized somehow.

dilation commented 4 years ago

Decoding (form ModelRepr) performance is pathological (probably exponential) for big models involving somewhat long products (probably also sums).

87 improves the situation by optimizing `ModelRepr#toModel`. However issues seem to remain: see #88 for reducing the serialized size of models; and see #89 for further improving `toModel` performance.
