Guys, I’d like to ask for your help!! 1. Test your connection between two computers 2. Indicate the protocol you used and what windows version(as well as hardware configurations, hub/switch/router, cabling, network interface card, hdd etc) 3. Use FreeMeter’s Disk throughput monitor (http://www.tiler.com/freemeter/Download/1_license.php) (it’s a freeware) to test how fast files get transfered between pcs 4. Indicate the average disk activity Im having problems, and I’m trying to isolate what the problem is. I have 3 computers at home with a CNET 8-port 10/100 network switch all connected with Cat5e UTP cables. The NICs are: CNET 10/100, D-Link 10/100, and Intel Pro 10/100. I’m also using IPX/SPX (NWLink), with File and Printer sharing unbinded from TCP/IP (I cant use TCP IP to share files since I have multiple IPs – my ISP gives 3 of them for free for one account). Now, I usually get only 5~6MB/s transfer speed, even if everything’s set at full duplex mode. A few days ago, I tried to isolate the problem. I made a crossover cable and connected two pcs together. I didn’t change the protocols and I STILL get 5~6MB/s transfer rate. I thought maybe it’s the fault of the IPX/SPX protocol so I removed them from both computers and I used Internet Connection Sharing to connect the two computers. I get a SLIGHT improvement about 6~7MB/s transfer rate. And then I also tried to use Network bridging but its speed is 6~7MB/s. I tried to use both CNET and DLINK to connect to the Intel NIC with no difference. Why can’t I get the speed to at LEAST 10MB/s???? 100mbits/sec is 12MB/s so where is my problem sourced??? Am I the only one experiencing this problem? Or what? Any suggestions people? Thanks! btw, All computers use Windows XP. With P3-933MHz 80Gig 7200RPM HDD and a Compaq 2800AP 1.4Ghz P4M Laptop.
