network speed
dongta77 Aug-17-00 08:17 PM
I have set up a LAN with 2 PC running 98SE on both. Every things looks fine, i can see both and can share internet connection. However, the speed is not look good to me. When I setup ftp server on host, the client transfer file (from host) at rate 200kbyte/s !!! I think i should get around 12Mbyte/s ..

Hub: 10/100 dual-speed 5 port hub
NICs: 2 Linksys Etherfast 10/100 LAN cards
cable: patch CAT5 100

Hi sorry I can't help you with your problem, I am new to the networking side of things, but I do have a question concerning the ftp server on your host. I would like to know how to set this up and is it accessable from the Internet, like other FTP sites?

Hi, I'm using FTP Serv-U as a ftp server. What you have to so just run the server and set up users. you can do a lot of things with FTP Serv-U, do a search on it ok...

is it accessable from the internet?? yes.. if you're using cable modem or any other connection which has static IP then you can access it by ftp to your IP, however if you're using dial up, your IP change every time you connect.. so if you want to ftp to you host you have to know your current IP.

I have not set-up and benchmarked FTP on a Windows LAN. How fast is it if you simply copy about 100 MBytes from one computer to the other with the Windows Explorer? See http://duxcw.com/digest/Reviews/Network/dlink/dfe-910/dfe-910_2.htm for some benchmarks. A slow LAN is usually caused by bad cables. Larry

Hi Larry
I did not try to copy a large file like that in Windows Explorer, but i tried a smaller file 10Mbytes. It took about 42 sec!!! I think the rate for 100Mb/s network is ~13Mbytes/s. So, 10Mb should only take me about 5 sec max right?? I tried a diffrent NIC (SMC-9432TX) but the speed is the same. is there any other setting i should set??
Using ICS is alright, i'm using Win98SE ICS, It works fine in 2 comp, host speed is 3.5kb/s and client speed is 2.7kb/s which is acceptable. I'll try SyGate today. Thanks

Try another cable. Larry

I presume the transfers are between hard disk drives and not between a CD-ROM and a hard disk drive? The problem could be caused by an IRQ conflict or shared IRQ, but that isnít likely. The only other suggestion I can offer is to start over. To eliminate TCP/IP as the problem, I would start by just installing the NetBEUI protocol and testing transfer speeds before proceeding further. Larry

yes, i'm using windows explore to copy between hard drive. I removed every things and just install NetBEUI on both computer. The speed is increase from 300kByte/s to 3Mbyte/s. But I think we can get faster than that for a small 100Mbps LAN (should be around 10Mbyte/s). what's wrong with my network?? thanks...

I get about 7 MBytes/s transferring from a 500 Mhz Windows 98 computer to an NT server. I am using an Ethernet switch so the transfers/handshaking are going at full duplex. Your speed is in the same ballpark so the problem probably is not now the network. The network is cannot transfer data faster than the computer can send it. Factors such as hard disk speed (ATA/33, ATA/66, 5,400/7,200 RPM), memory, CPU speed, etc. enter into the equation. When was the last time you defragged your hard disk drive. Do you have a CD-ROM drive on the same cable as the hard disk? Do you have use DMA checked in Control Panel, System, Device Manager, Device Manger, Disk Drive, Properties? In other words, look at the computers for performance gains. Larry
