I've been using VDP for the past few years (on the latest version). My backup and replication jobs are running fine, and I perform backup restores about 4 to 8 times a year.
The web access has always been slow. It takes about 15-20 minutes to load the backup jobs tab. And every time I make a change to a backup job the screen has to load again and it takes another 15-20 minutes. What's the deal? Is this normal for you guys?
All my backups are currently going to a Data Domain. I have about 12 jobs that backs up 28 VMs. Can anyone help me figure out why it takes that long to load up the backup jobs list? This also happens in the restore and report tab as well.
Could be a bug in VDP.
Slow response from the VDP User Interface fixed in VDP 5.8 - see vSphere Data Protection (VDP) and VDP Advanced 5.8 Release Notes
Slow with Recovery wizard fixed in VDP 6.1 - see vSphere Data Protection 6.1 Release Notes
Loading clients takes a significant amount of time when editing or cloning a backup job known issue will be fixed in future release- see vSphere Data Protection 6.1 Release Notes
I had/have a similar problem, the VDP web UI being dismally slow (more so that the already glacial vsphere web client itself)
Turns out my VDP VM was swapping.
I cranked up the RAM allocated to the VM, and it improved performance quite a bit.
No idea if that's the same thing you are seeing, but it helped in my case, so figured I would pass it along.
