Re: Speed performance!!
If you supernet you will put all stations on one segement. Your network would not slow down but come down. You need to look to some switching design with fastether channel to the server.

RE: Speed performance!!
If you are using a Cisco router what type of switching is it using of the interfaces in question, process-switch, fast-switch, etc. ? Take a look at the interface and processor utilization as well, and the number of broadcast and errors on those segments. I have found those are more likely causes of poor performance than packets being routed. sho int sho proc cpu Carlton -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of jeongwoo park Sent: Friday, November 03, 2000 6:57 PM To: Groupstudy Subject: Speed performance!!

Re: Speed performance!!
JW, be more specific about your network topology. Where are the users in reference to the server? What type of network hardware are you using (hubs, switches, etc.) and with is the type and speed of your WAN links if any?? If you network does not have the adequate horse power and bandwidth to handle the load needed to access the server, summarization will not help much. Granted it helps in optimizing routing but if 600 users are trying to access a server on a hub, you are still going to suffer. jeongwoo park wrote: 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.

Re: Speed performance!!
Wow..Two questions. What is doing your routing and What program is doing the file transfer?

RE: Speed performance!!
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.
