I'm noticing that after upgrading to 4.3.8, sometimes the dashboard is very slow and it takes minutes to display and to let me work, even if I'm not interested at all to the dashboard for the activities I have to do.

As a consequence it becomes a bottleneck.

On engine I see that during these moments the postmaster process related to ovirt_engine_history database is 100% cpu consuming.

Almost every minor update I run vacuum but I don't know if there is something else involved.

Is there any bug open with in in 4.3.8?

Is there any option to set another page as the landing one when I open web admin portal?

I have similar problem on a RHV environment where I have done upgrade form 4.2.7 to 4.2.8 and then 4.3.8 in the same day (eventually I'm going to open a case fir this one).

When passing from 4.2.7 to 4.2.8 I chose full vacuum for the engine history database:

          Perform full vacuum on the oVirt engine history
          database ovirt_engine_history@localhost?
          This operation may take a while depending on this setup health and the
          configuration of the db vacuum process.
          See https://www.postgresql.org/docs/9.0/static/sql-vacuum.html
          (Yes, No) [No]: Yes

while I chose NO during the upgrade from 4.2.8 to 4.3.8 that I've done half an hour later.

Thanks in advance,

Gianluca
