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.

radtest
RADTEST(1) FreeRADIUS Daemon RADTEST(1)
NAME
radtest - send packets to a RADIUS server, show reply
SYNOPSIS
radtest [-d raddb_directory] [-t pap/chap/mschap] [-x ] [-4 ] [-6 ] user password radius-server nas-port-number secret [ppphint] [nasname]
DESCRIPTION
radtest is a frontend to radclient(1). It generates a list of attribute/value pairs based on the command line arguments, and feeds these
into radclient. It's a fast and convenient way to test a radius server.
OPTIONS
-d raddb_directory
The directory that contains the RADIUS dictionary files. Defaults to /etc/raddb.
-t pap/chap/mschap/eap-md5
Choose the authentiction method to use. e.g. "-t pap", "-t chap", "-t mschap", or "-t eap-md5",. Defaults to "pap". Using EAP-MD5
requires that the "radeapclient" program is installed.
-x Enables debugging output for the RADIUS client.
-4 Use NAS-IP-Address for the NAS address (default)
-6 Use NAS-IPv6-Address for the NAS address (default)
user Username to send.
password
Password of the user.
radius-server
Hostname or IP address of the radius server. Optionally, you may specify a port by appending :port
nas-port-number
The value of the NAS-Port attribute. Is an integer between 0 and 2^31, and it really doesn't matter what you put here. 10 will do
fine.
secret The shared secret for this client.
ppphint
If you put an integer > 0 here, radtest (or actually radclient) will add the attribute Framed-Protocol = PPP to the request packet.
nasname
If present, this will be resolved to an IP address and added to the request packet as the NAS-IP-Address attribute. If you don't
specify it, the local hostname of the system will be used.
SEE ALSO
radiusd(8), radclient(1).
