> Key: LIBCLOUD-826

> Project: Libcloud
> Issue Type: Improvement
> Components: Compute
> Reporter: Tom Melendez
> Labels: gce
>
> list_nodes currently makes at least one independent API call to the disks/get
> API (to obtain disk information) for each node in the list. This change will
> use the disks/aggregatedList API for this instead, reducing NUM_INSTANCES API
> calls to one.
> I ran some simple command-line tests to demonstrate the improvements in
> response time and API calls.
> Below is an in-network comparison using 40 nodes in 4 different regions.
> ||Code||instances/zones/regions||Time (sec)||API Calls
> |Current 1.0|40/4/2|6.805|43|
> |with disks/aggregatedList|40/4/2|0.919|4|
> I have a PR forthcoming to implement this.
