Perderabo is correct about the network topology situation. However, you might be able to check network throughput while copying a file or some other large bandwidth intensive task and get a quick idea of your actual throughput with netstat. I have never tried it under Solaris, but it works like a champ under FreeBSD.

Code:
netstat -I <interface> <seconds>

Where <interface> is the interface and <seconds> is the delay between updates.

Example:

Code:
FreeBSD:auswipe:/home/auswipe $ netstat -I rl0 1
            input          (rl0)           output
   packets  errs      bytes    packets  errs      bytes colls
         2     0        132          0     0          0     0
         1     0         66          1     0        178     0
         1     0         66          1     0        178     0
         1     0         66          1     0        178     0
^C
FreeBSD:auswipe:/home/auswipe $

Obviously I'm not pushing much on my local network when I ran this.

Name
       ris - remote installation services utility

Syntax
       /etc/ris

Description
       The  utility performs remote installation services which install system software to a client machine through the TCP/IP local network.  The
       client machine can be a VAX or a RISC machine.

       The server on which the remote installation services area is located can be either a VAX or a RISC machine.

       The remote installation services utility uses the directory as a base.  When you install the first product to the utility creates a  remote
       installation services area.  The area is called either or

       The  area contains one or more ULTRIX software products.  Each product contains the subsets of the kits that can be installed to clients on
       a network.  Clients registered for an area install software over the network to their processor.

       The utility performs the following functions:

       a -  Add client

       r -  Remove client

       s -  Show products in remote installation environments

       m -  Modify client

       i -  Install software

       You must use the utility interactively to set up a remote installation services area.  After you have set up a remote installation services
       area on the server, you can use the utility either interactively or from the command line to manage clients.

       The directory also holds a subdirectory, This directory contains a database file, that you can use to manage multiple clients.

Examples
       The example that follows invokes the utility interactively:
       # /etc/ris

       A menu appears from which you can select options to perform functions.

       The examples that follow manage the client using the command line.

       The syntax of the command to add a client follows:
       /etc/ris -a <clientname> -h <Ethernet_address> -p path,product[,product]

       The following command adds client and allows that client to install a product over the network:
       # /etc/ris -a bergal -h 08-00-2B-03-05-8B -p ris0.mips,product_1

       The syntax of the command to modify a client follows:
       /etc/ris -a <clientname> [-h <Ethernet_address>] [-p <path,product,product>]

       The following command modifies client and allows that client to install a product over the network:
       # /etc/ris -m bergal -p ris0.mips,product_2

       The syntax of the command to remove a client follows:
       /etc/ris -r <clientname>

       The following command removes client
       # /etc/ris -r bergal
