Bug Description
canonical_url is thought to perform poorly (quadratic behaviour due to traversing on every call). A ++profile++ trace would help confirm this.
the canonical_url for an object is constant within a readonly (GET) request. So one possible solution is to cache the result for a single transaction of canonical_url on each object.
