Hi
I discussed it with Juan (cc-ed).
There used to be a bug in the JDBC authenticion extension thatartificially delayed RESTAPI responses by 5 seconds: brute force prevention login delay should not be applied to successfullogin requests https://bugzilla.redhat.com/1255814That matches the description of the issue, but in theory it has beenfixed. I would suggest him to check that he is using the right versionof the extension.In addition we also know that retrieving large lists of objects with theSDK is slow: [RFE][performance] - generate large scale list running to slow. https://bugzilla.redhat.com/1221238We don't have a solution for that yet.
CC-ing Juan in case you have additional questions.
