To throw more confusion onto the whole setup, when I used intel 100M cards over a switch, I could easily get upto 4MB/sec data transfer for large files. The same machines with Compex cards using some wdxxx chipset would give 300k under linux, but around 2MB under windows (The linux driver was surely faulty). A RealTek rtl8139(or 29??) based cheapo card would max out at 2MB/sec on win-win, win-lin & lin-lin. All these speeds were measured using ftp file transfers for large files and idle systems. The 4mb/sec speed of the intel cards seemed to be because of the disk throughput. I wonder if the intel cards use significantly less cpu to cause such good speeds. On another note, i have transferred a 700MB file from a win2k workstation having a 3com 100M card to a compaq server having hardware raid 5 and connected to a gigabit switch with gigabit cards in around 2-3 mins. Which is roughly 4-5mb/sec. The RAID system on the server was using 10k rpm drives and had 6-7 or more hdds in the array. So i suppose that the hdd speed is a limiting factor. I am right now thinking about getting 4 80gb 5400 rpm drives and then setting up my celeron 366 on raid 5, raid 1 and raid 0 to see the performence i can get out of normal dlink 100mbps cards. That way i will be able to measure the effect of lan throughput, cpu speed and linux + samba + win2k ;) Ambar Roy _______________________________________________ ilugd mailing list [EMAIL PROTECTED] http://frodo.hserus.net/mailman/listinfo/ilugd
