vcenter 7.0 on dswitch slow to display hosts and port groups

I have a clean install of 7.0 that I migrated to a host with dswitch and dswitch iSCSI networks. After moving vcenter into the dswitch everything works, but I noticed when adding another host into the dswitch the screens slowed down significantly and take 10-20seconds on a few screens. Primarily when loading the available hosts and loading the distribution port group screens. Applying the changes takes 2-4ms and these are the only screens where I see the slowness. Traffic between the hosts and storage are all <1ms. Right now I only have 1 vm on the hosts (the vcenter vm).

Anyone else see anything like this?

I tried to test this out in my lab and I didnt see any latency or delay in retrieving the list of the available host / portgroup.

Can you please upload the vmkernel log ,vobd.log, hostd.log  of the host where the VC sits

also upload the vpxd logs with the timestamp
