Title:
fernet token validation is slow
Status in OpenStack Identity (keystone):
Expired
Bug description:
keystone token validation operations are much slower than uuid
operations. The performance is up to 4x slower which makes other
openstack API calls slower too.
Numbers from Dolph:
Token validation performance
Response time Requests per second
UUID 18.8 ms (baseline) 256.7 (baseline)
Fernet 93.8 ms (400% slower) 48.3 (81% slower)
My numbers running on a basic setup running keystone in a VM without a load
balancer:
Tokens per second (serial):
UUID: 14.97
Fernet: 3.66
Tokens per second (concurrent 20 threads):
UUID: 46.18
Fernet: 12.92
Our numbers are similarly bad in production and its impacting
OpenStack performance when we're under load.
