I don't think supernet will solve this problem! One of the purposes of Aggregate route 
is to reduce router's
memory and stable network. You still have four subnets and router will route these 
traffic. 

My suggestion is :

         1. Check Router forwarding rate( upgrade router ).
         2. Implement Queuing in your router.
         3. enable ip route cache in each interface. 
         4. Check file server's CPU utllization.
         5. Check file server NIC and switch port setting( 100/10, Full/half ).
         6. Check backbone capacity.
         7. filter unnecessary protocols in the network.

Hi all
My file server is on 140.222.20.1/24
Clients are on these four subnets.
140.222.150.0/24
140.222.181.0/24
140.222.237.0/24
140.222.200.0/24

There is such a slow data transfer rate going from any
of these 4 subnets to the subnet where the server is.
All clients get DHCP ip addresses
As a suggestion, someone told me to supernet.
As far as I know, in order to supernet, subnet ip
addresses should be contiguous, and I think the idea
of supernetting is to include multiple subnets into
one supernetted subnet. So we can transfer data within
one subnet instead of transferring through router for
subnet-to-subnet transfer. 
However, these five subnet ip addresses are not
contiguous.
How can I supernet non-contiguous subnet ip addresses?
By following Cisco book instruction on supernetting, I
got this address: 140.222.0.0/16 Is this correct?
If this was correctly supernetted, what should I do
next?
Should I go to each individual stations (about 600
stations) for new TCP/IP setup? I am sure there should
be better way to handle this.

I have only several months of network experience. I am
still newbie.
I will appreciate your help
Thanks in adv.
