Please help! Message-ID: <0039010009149140000002L102*@MHS> Date: Mon, 25 Oct 1999 15:32:15 -0400 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: quoted-printable Content-Disposition: inline Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I'm currently running FreeBSD 3.2 on a custom-built Pentium-II 350 MHz = PC with 64 MB SDRAM, Western Digital 4.3G HDD, Acer 32X CD-ROM, Trident 975 AGP= video card and an Intel EtherExpress Pro 10/100B NIC connected to our etherne= t network (100MB/sec). The PC is our company's Intranet server (www/ftp/dns/qmai= l/mysql) so throughput is important. Network performance on this server has bee= n very unsatisfactory, to say the least. I've obtained a maximum of 100k/sec = (average of 50k/sec) while ftping files onto the server or downloading files fro= m the server. When I first installed FreeBSD, I had a 3Com 3C905B-TX NIC in = the computer. Soon after I finished the installation of FreeBSD, I noticed= the poor network performance. I figured I did not have the correct drivers inst= alled for the 3Com NIC and decided to create a custom kernel. I followed the ker= nel configuration howto found on the FreeBSD.org web page very carefully. = I commented out the lines corresponding to the network cards I never plan= ned on using in the future and left support for the 3Com 3C905B-TX and the Int= el EtherExpress Pro 10/100B NICs in the kernel. I booted to the new kerne= l and still experienced the slow network performance. I checked the ifconfig= output for the xl0 device to make sure it was using 100baseTX , w= hich it was. I was stumped since I originally had Red Hat 6.0 installed on the= exact same server and the throughput under Red Hat was exceptional. The only= thing that had changed was FreeBSD. The next thing I tried was switching out= the 3Com card for the Intel card (I had this card in another system so I know it= is a good card). I made sure the following lines were in my /etc/rc.conf fi= le: ifconfig_fxp0=3D"inet 170.0.11.100 netmask 255.255.0.0 media autose= lect" network_interfaces=3D"fxp0 lo0" and the following lines were in my dmesg log: fxp0: rev 0x08 int a irq = 10 on pci0.11.0 fxp0: Ethernet address 00:90:27:7b:c1:28 I greatest speed I could achieve with the Intel card was the same as th= e 3Com card (max of 100k/sec). I don't know where to go from here. I'm very = new to FreeBSD so please bear with me. Let me know what additional informatio= n would be helpful to diagnosing this problem. Thank you!
