Description ojanas 2018-07-09 11:35:49 UTC
Description of problem:

The neutron API responses are slow when there is a lot of resources in database (neutron ports for example). Listing of all of the ports takes ~35s.

Is it possible to do some optimizations so the API responses faster?

Version-Release number of selected component (if applicable):


Actual results:

The neutron API response is slow

Expected results:

The neutron API response is faster

The octavia Squad indicates that something similar was happening in octavia, and they fixed it this way:

It's still unconfirmed if it's related, but I'll leave it here for just in case.

BTW, question, do we know if horizon is requesting items to neutron with pagination?, ideally it should use pagination to avoid loading many items it's not going to display.

Re-assigning to Nate.  Once oslo.policy fix is confirmed this can move to that component for backport.
