Subject [jira] [Commented] (JCLOUDS-357) ComputeService.listnodes() in the case of softlayer cloud takes about 2 minutes for cloud with only 3 machines

    [ https://issues.apache.org/jira/browse/JCLOUDS-357?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13818756#comment-13818756

Eli Polonsky commented on JCLOUDS-357:
--------------------------------------

I will definitely try this.

but dont you think a feature like i mentioned is worth having? 

this of this: jclouds.NodeMetaData.location = false, would leave the location field null for
the VirtualGuestToNodeMeta conversion. you can also have it apply to nested fields like:
jclouds.NodeMetaData.location.id = false.

So basically a simple implementation would be to define an interface that includes methods
for all populate fields actions and call each method based on these properties.
Only this is that i am not sure how this fits exactly into the current design.

But this feature should be very useful, it gives the users much more flexibility to different
kind of environments without having to compile any code.

>             Project: jclouds
>          Issue Type: Improvement
>          Components: jclouds-compute
>    Affects Versions: 1.5.10, 1.6.2
>         Environment: Windows 7 64-bit
>            Reporter: Evgeny Fisher
>            Priority: Critical
>              Labels: softlayer
>
> The significant delay is on the following call: method apply(VirtualGuest) of 
> org.jclouds.softlayer.compute.functions.VirtualGuestToNodeMetadata 
>  findLocationForVirtualGuest.apply(from).
> If I removes in above calling initializing location within builder then it improves performance
dramatically: instead of 2 minutes it takes now about 12 seconds in order to bring 3 nodes..
> Performance is improved as well if in addition to location the following fields of builder
are not initialized: operatingSystem, hardware, group.
> I think initializing of of these builder fields should be optional, since like in my
case I need only id, hostname, public IP and private ip.
> I'm aware that next calls will go to cache and will have much better performance, but
I need good performance already during first call.
