I discussed it with Juan (cc-ed).

There used to be a bug in the JDBC authenticion extension that
artificially delayed RESTAPI responses by 5 seconds:

  brute force prevention login delay should not be applied to successful
login requests

That matches the description of the issue, but in theory it has been
fixed. I would suggest him to check that he is using the right version
of the extension.

In addition we also know that retrieving large lists of objects with the
SDK is slow:

   [RFE][performance] - generate large scale list running to slow.

We don't have a solution for that yet.

CC-ing Juan in case you have additional questions.

Hi guys,

I am using the ovirt-engine-sdk-python to communicate with the ovirt-engine,
I am ok to list the vms but the processing time is too long, like 4.5 seconds,
and this line:
    from ovirtsdk.api import API
take almost 3 seconds.

This seems a little bit longer than I expected it to be, so I am asking is there
a quicker way to communicate with the ovirt-engine?
