Attempting to access the page for a series on a project can timeout; https://launchpad.net/bugsy/development/ continuously times out for me. This makes it rather difficult to add new milestones.
Here is a few of the OOPs:

So death-by linear-lookups in expose_user_administered_teams_to_js |
Summary
=======
A quadratic-in-teams scaling function was added during the new subscriptions work. This regressed page performance on pages that trigger expose_user_administered_teams_to_js. Additionally this page itself is running the function multiple times due to this call stack:
lp.registry.browser.milestone:212(initialize)
expose_structural_subscription_data_to_js
expose_user_administered_teams_to_js
So each milestone view created is running the function and the function is slow (foo in a-list triggers quadratic lookup overhead). Fixing the repeated-invocations should provide significant amelioration.
