Yes, I currently have some houses & an office building which are 396, 520, & 600-700 prims each on Region. They all have linked doors & linked lighting systems (scripted control interfaces) and all operate without issues or delays. I did have some issues previously but those were resolved over that past year with some of the OpenSim refactoring that Justin Casey-Clark did.
I have 2 other questions for you... do you use a code repository like Github, Bitbucket ?
Have you seen, heard of or used HPA Backup ?
HPA is a hybrid backup system which also encapsulates prim contents like scripts, notecards, textures but not objects within objects. I'm not certain it could coexist with XML backup in teh viewer, possibly could (which would be amazing) but HPA has the advantage of sull backup & objects contents which XML can't handle.
Presently Angstrom (V3 based) bas HPA, a version of Astra (based off Singularity) have it. Seems there may be issues with the licencing (the nightmare we all have to endure) but I'm not 100% certain on licence issues, other than they give me migrain headaches.
In case your interested in having a quick peek, I think the code is "fair" but likely could use some delicate loving to improve it. Your special brand of je ne ces't quoi,
Here is Angstrom on BitBucket:
