hello,

there is no load that the first point, so maybe it is just some spikes.
are there any reason to be worry about it ? slowness of the interface anything like that ?

ya. the interface is working slow especially clicking a new mail.
Sometimes a popup is showed, it states that the server is still working or u want to cancel the request.

You should investigate on your sizing (CPU, RAM) the type of your volume disk ect.
Check the log system and zimbra.
