When generating the routing map, `Rule.add` will call
`Rule._compile_builder` twice, representing almost one third of the
routing map generation time. `_compile_builder` is actually stored
in `Rule._build` and `Rule._build_unknown` for latter use, in the
`Rule.build` method.
The `Rule.build` method is used to transform a rule, lets say
`/forum/<model("forum.forum"):forum>` in `/forum/basics-of-gardening-2`
Even if a deeper investigation could be interresting, it looks like it
is only used for `is_frontend_multilang` routes and `_enumerate_pages`,
used in the `sitemap` and `search_pages`.
The proposed solution si to make this part lazy, in order to call
_compile_builder on demand, once per rule. This will speedup the initial
routing map generation and postpone the heavy work when we need it,
only for the part we need most of the time.
On a database with all modules installed, generation of the routing map:
Before: ~600 ms
After: ~200 ms
An alternative implementation was also overriding the Rule.build method
instead of having a callable LazyCompiledBuilder, this implementation
was choosen since it is less dependant off the werkzeug implementation.
