Revit 2019 slowdown/jamming/freezing during mornings, but not afternoons 🤔

[Anonymous]

Hi all y'all!

A colleague of mine (user A) is editing a (shared) .RVT file with his HP Zbook laptop (i7 CPU, AMD Radeon WX 3100 2GB GPU, 16GB RAM, Win10 x64, Gigabit ethernet). The model resides on the office's local server's network share, and all users are editing it using the same LAN.

Another user (user B) is experiencing similar issues, but less severe, so I'll focus on user A. They both have virtually identical laptop rigs they're working on. There are other users with identical or nearly identical laptops, in the same LAN, who aren't having the same problems.

When highlighting elements in the model, hovering over them with the mouse, this can cause Revit 2019 to freeze for 10-30 seconds, or even a minute or two. It can get the "(not responding)" status on the title bar. The same thing happens when zooming. 

Bizarrely, this only seems to happen during the mornings. For whatever bizarre reason, in the afternoon, the same laptop seems quite able to handle the model, without a hitch.

At no point do the laptop's "Resources" get overwhelmed, looking at Windows 10 Task Manager. CPU, GPU, RAM, all of them are usually at less than 60% capacity. Nor do the Windows Server computer's resources seem to be too burdened.

Does anyone know Revit's "under the hood" stuff enough to have any clue, intuition or insight into what could cause this sort of slowdown? And what could possibly be done to fix it?

The RVT is a pretty large (but not crazy large), 200MB stucture, with some detail work.

Thanks in advance for sharing any insight!

It really depends on your office IT and what is running at the background. From my side, I experience the complete opposite where it is fine in the morning and slow down in the afternoon. I check with IT and usually it happens when the backup system is creating an image of the server files. This may lead to slowdown for few seconds. Check with your local IT and see what they are doing from their end that cause your file to slowdown in the morning.
