When viewing default rules, the clips really drag now in being listed, and the program freezes up. This freeze was noticed after upgrading on the 2012 server right away from the 3 version to the next verion as well as the followup verion 4-1 and then 4-2
So as a test I installed a new VM of 2008 server as it's much more simplistic in it's code base. Immediately the slowness was noted (Fresh domain connect VM fully updated etc) with plenty of resources.
The server is accessible through RDP if necessary to test this.
There is only one camera and it's configured identically as before. It's a Hikvision 2CD2532F-IWS
The program is reporting freezing (As it did on the other installation) when viewing clips. It's unuseable for clip viewing (On the 2012 server I used a Ramdisk to speed up the slow performing clip reviewing) and at did speed up the listing. The slowness started with the upgrade, and is reproduceable with the new VM with the latest SH.
I don't notice a spike in disk, cpu or mem usage through the hypervisor manager nor in the VM with resource manager.
Web Interface, same issue with clips
