I use FUSE and I have nearly 1000 clients.

I have over 1M files and %13 of cluster is used which makes average
file size 1GB.
Minimum/Maximum file size is 100MB/2GB.
Every day 10-20TB new data enters the volume.

Metadata operations are slow as you expect. I try not to put more than
2-3K files in a directory.
My use case is for backup/archive so I rarely do metadata operations.
