sing Devstack (Grizzly-3) and nova SHA1 98f9f735d7e6ac32a8736971f4aab0d81c56131e
euca-describe-instances (POST /services/Cloud/ CloudController:DescribeInstances) is 13 times slower than nova list with 700 VMS.
This is because s3_image_get_by_uuid is called three times per instance and
block_device_mapping_get_all_by_instance,
block_device_mapping_get_all_by_instance,
aggregate_metadata_get_by_host,
get_ec2_instance_id_by_uuid
are called once per hose.
So for 700 VMs that is 4900 DB calls! |

In comparison 'nova list' does 2 DB calls no matter how many VMs there are. |

When running the same thing as demo user I get the same thing |
