Hello, I upgraded my SOHO network to 100 Base T HalfDuplex network and I am running a nonswitching 100 Base T only-HUB. All ethernet boards are forced to work in half-duplex mode. I have one linux-server and three clients, two Windoze clients, Win95 and one Win98 client, and one linux-client 2.0.36 on the LAN. The linux-server is running linux 2.0.36 SuSE 6.0 (Pentium MMX200MHz, 96MB RAM). 100M ethernet-boards used: Linux server is using epic100.c driver SMC Ethernet II. All other are Realtek boards 8139. MY PROBLEM SPEED: ftp transfer rates (200MByte file for testing): wu.ftpd is running on linux-server, started by inetd. FTP-32 client version 95.08.19 from John A Junod. linux client to linux-server both directions 3.5 MByte/sec linux-server to Win95/98-clients upload 3.5MByte/sec SLOW SLOW:: !!!Win95/98 ftp-client upload to the wu.ftpd daemon running on linux-server results in 1 MByte/sec !!!!!! transfer rate :-((( RUNNING two uploads from two different Win95-PC clients in parallel : each transfer speed 1 Mbyte/sec!! Thats very strange! Win95 download/upload to Win98 (using exceed ftpd on either pc) 2.3 Mbyte -->> BETTER than linux ?? ifconfig reports no errors/overruns on the SMC device. I changed via route the window and segment size: no effect. I changed in the SMC-driver the receive-buffer count and size: no effect. For testing I connected the linux-server crossover to the Win98 client and made an upload from the Win95 client to the linux-server and got the 1MByte/s as well :-((((. NO collisions at all!!! I changed the cables : no effect. SO THE HARDWARE IS OK but linux is so slow WHY? I DON'T WANT TO GO BACK to WinNT!! I argued to my boss that linux is as fast as NT but I loose.... Please help somebody: Is this a known problem? Does somebody else has the same effect? What kind of info does someone needs from me to come to an idea what the cause of the problem is? What can I do to get more performance for upload to the linux-server from the windows clients? Thanks for reading so far.
