Collaborate in 2018.3.0f2 Losing Performance

My team and I used to work on the 2017 LTS version, but as we started a new project we decided to venture into 2018 because there were several improvements that we care about. But we use Unity's own Collaborate system to do our work, and what happens is that if we're logged into our accounts, the performance loss is significant, as if 500fps were for 10fps, and our solution for that problem is simply to work Unlogged, which generates more work, because we have to Log in again one hour to be able to go up to our cloud the changes, wanted to know if the Unity has some hot fix for this, or if they want to fix this in the 2019 version

Best Regards.
