There are only so many components involved, so the debugging should be straightforward:
How is the NAS connected to your system? I suppose it is an NFS-mount, no?
If so, the following has to be checked:
- network equipment: scp a larger file somewhere to test. Measure time.
- name resolution: put NAS server into /etc/hosts and have local files (=/etc/hosts) take precedence over DNS in /etc/resolv.conf
- mount options: look carefully how the FS from the NAS is mounted. Typical problems include CIO (concurrent I/O), user authentication via outside sources (i.e. user authorization via Kerberos and a slow, unresponsive Kerberos server) and the like.
- If you use NFSv4 (you shouldn't - it is crap) check the NFS-domain. It has to be set on every client and server.
I hope this helps.

rlm_acct_unique
rlm_acct_unique(5) FreeRADIUS Module rlm_acct_unique(5)
NAME
rlm_acct_unique - FreeRADIUS Module
DESCRIPTION
The rlm_acct_unique module creates a unique accounting session Id.
Many NAS vendors have their equipment supply an Acct-Session-Id attribute which is not unique over reboots. This makes accounting diffi-
cult, as there will be many independent sessions with the same Acct-Session-Id attribute. This module uses the Acct-Session-Id attribute,
along with other attributes in the request, to create a more unique session ID, called Acct-Unique-Session-Id.
The main configuration items to be aware of are:
key A list of the attributes used in calculating an MD5 hash which is used as the value for the unique session id.
CONFIGURATION
modules {
...
acct_unique {
key = "User-Name, Acct-Session-Id, NAS-IP-Address, NAS-Port"
}
...
}
...
preacct {
...
acct_unique
...
}
After generating the MD5 hash, the module adds it to the accounting request packet received from the client. It will look something like
this in your detail file:
Acct-Unique-Session-Id = "c66ef57e480b9d26"
NOTE: Any attribute you specify that is not found in the 'dictionary' file will cause the server to fail and exit with an error.
NOTE: If you want the Acct-Unique-Session-Id of the Start and the Stop packet of a particular session to match, you must use values for
the key that will stay the same for the Start and Stop. The above example is a good start. Adding 'Acct-Session-Time', for example, would
cause a mismatch because that value is not the same on the Start and Stop accounting packets.
