[ovirt-users] Slow first opening web portal when the ovirt-engine.service is restarted

[aleksey.maksimov at it-kb.ru]

Hello oVirt guru`s !

oVirt Engine Version: 4.0.4.4-1.el7.centos

After restarting the ovirt-engine.service, the web login page is available after a few seconds. That's good.
But when trying the first login, the portal web page open for 2-3 minutes

All subsequent logins are fast.

The question is: Why is the delay in the opening pages of the first call?

Do I understand correctly that this feature of JBoss web application?
Need some warming up of the web application?
