[Pete Muir (JIRA)]

Pete Muir commented on WBRI-357:
--------------------------------

An obvious performance hotspot is assignability. It is called for every resolution and more. However, given we cache all resolutions, this may only affect deployment time significantly - this would need verifying, and more caching used if necessary.

If it is only a deployment time issue, caching may help, but may also just affect scalability with little improvement as a particular check may only be used once.

Options for improvement are limited, but include checking short circuit loops where possible and look at faster algorithms. Another option is to look at performing assignability checks in other threads.
