Hello Felix,
firstly, thanks for your email we would more than happy to change it,
but the opennebula driver is managed by OpenNebula guys, so surely
they're looking at this mail and they will be more than happy to fix
the issue.
Obviously, if you want, you can send a patch if you think would solve
the issue and if match the criteria will be accepted :)
Cheers,
Francesco Vollero

Dear All,
I am new with deltacloud, for integration requirement, we are evaluating
deltacloud solution.
Here, I don't know if anybody ever reported this issue, however, recently, I
noticed deltacloud is in poor performance with our open nebula instance.
Usually, our opennebula always runs over 500 VM instances, and while we use
deltacloud to query instances, it will take pretty long time to get all
results.
Here are some examples:
With "deltacloudc instances" command:
real 20m19.293s
user 0m7.842s
sys 0m0.681s
With curl to deltacloud rest api "/api/instances":
real 4m35.891s
user 0m0.002s
sys 0m0.005s
With curl to opennebula OCCI interface "/compute" directly via the same
host:
real 0m1.249s
user 0m0.001s
sys 0m0.006s
It seems to me that the REXML will be the performance bottleneck in
opennebula_driver, so, would you consider to replace it by another one?
BTW, I am using following deltacloud version:
deltacloud-client (0.5.0)
deltacloud-core (1.0.0)
And my ruby version is 1.9.3p194.
OS is Scientific Linux 5.8 with 2.6.18-308.8.2.el5 kernel.
