Description bigswitch 2017-06-28 13:43:49 EDT
Description of problem:
We are trying to scale RHOSP 10 with 900 projects, one logical router per project, and four network with one subnet each per tenant with a script.
The setup has three controller and one compute node deployed. Each controller has 48 cores and 380gig ram.
The script creates 900 tenants first, than attempt to create 900 logical routers and fail at about 150 logical routers. It than attempts to create 4 networks per tenant and at about 400 networks/subnets it is seeing 504 gateway timeout error. There is also DBDeadlock error in neutron-server log.
Would like to know if there is any settings we can tweak to improve the database performance.

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

How reproducible:

Will upload sosreport from three controllers to box.
