Is this per connection? How many clients connect to that
system? If you are using SMB1, the protocol has a 16-bit
field for file IDs, this effectively limits the maximum
number of files to 65536. In the real world it will be a bit
less. With SMB2, there's no such limitation, but I don't
know where people have pushed this so far.

Not really. Do you have a bit more information about your
workload, so that we can test this and lift limits?

Thanks,
