I would actually disagree here, as I've seen numerous reports in the past years where it was taking over 24 hours. No Veeam in the picture - just admins chatting on VMware Communities worrying about "stuck" snapshot removal task in vCenter.
It important to realize this is not always about the size of snapshots. It could also be due to overloaded primary storage and busy VM, which results in snapshot removal process unable to catch up with the new writes (there are certain snapshot size and storage performance thresholds before hypervisor will allow VM stun for that final aux snapshot commit, to ensure stun time remains acceptable).
Luckily, most of that stuff is a thing of the past now, after VMware had completely re-architected snapshot removal in the latest vSphere releases by reusing the code for Storage VMotion, which allowed new writes to go straight into the base VMDK instead of a snapshot file.
