Hi I have a newly installed freebsd box and an NT box on a local net When I ftp between the 2, I only get 50-80k/sec which is undesireable Even a stinking dos box does this much, with little or no buffering. Does anyone have any ideas???? Below are details to help diagnose prob. and kernel config file just in case thats of use (maybe I messed up on one entry) Both boxes are load free as is the wire I see no collisions at LEDS on back of ne2000 card The freeBSD box has 16M and a slightly modified kernel (only deletions and addition of a multiport serial card) and is otherwise fast as hell. The NT box is probably not the problem either as it is 3.51 and has run wonderfully for a long time. I have tried both ne2000 and 3com 509 cards in both and this is not the problem. The cable is terminated 6ft of rg58 thin net (one bud said something about too short a cable. Thats a new one, but considering..... ) when I kill gated transmission speeds up??? ( +20-30k/sec) when I transfer multiple large files they progressively get slower Pings average under 1ms. transfer (viewed via hash) is sporatic with a maybe 10 K at first, pause and several burst (~60k) at the rate I would expect with 1-1.5 sec pauses inbetween with little or no trasfer durring that time. Basically HELP..... Dont know enough to straighten it out. Others I know have nearly same setup and no problems (except low end cards == <500k/sec) --------------------- heres the modified kernel config file -------- # Modfide # GENERIC -- Generic machine with WD/AHx/NCR/BTx family disks # # GENERIC,v 1.45.2.3 1995/06/05 21:50:41 jkh Exp # machine "i386" #cpu "I386_CPU" #cpu "I486_CPU" cpu "I586_CPU" ident NewKernel maxusers 64 #options MATH_EMULATE #Support for x87 emulation options INET #InterNETworking options FFS #Berkeley Fast Filesystem options NFS #Network Filesystem options MSDOSFS #MSDOS Filesystem options "CD9660" #ISO 9660 Filesystem options PROCFS #Process filesystem options "COMPAT_43" #Compatible with BSD 4.3 options "SCSI_DELAY=15" #Be pessimistic about Joe SCSI device options BOUNCE_BUFFERS #include support for DMA bounce buffers options UCONSOLE #Allow users to grab the console config kernel root on wd0 controller isa0 controller pci0 controller fdc0 at isa? port "IO_FD1" bio irq 6 drq 2 vector fdintr disk fd0 at fdc0 drive 0 disk fd1 at fdc0 drive 1 tape ft0 at fdc0 drive 2 controller wdc0 at isa? port "IO_WD1" bio irq 14 vector wdintr disk wd0 at wdc0 drive 0 disk wd1 at wdc0 drive 1 controller wdc1 at isa? port "IO_WD2" bio irq 15 vector wdintr disk wd2 at wdc1 drive 0 disk wd3 at wdc1 drive 1 #controller ncr0 controller ahc0 #controller bt0 at isa? port "IO_BT0" bio irq ? vector btintr #controller uha0 at isa? port "IO_UHA0" bio irq ? drq 5 vector uhaintr #controller ahc1 at isa? bio irq ? vector ahcintr #controller ahb0 at isa? bio irq ? vector ahbintr #controller aha0 at isa? port "IO_AHA0" bio irq ? drq 5 vector ahaintr #controller aic0 at isa? port 0x340 bio irq 11 vector aicintr #controller nca0 at isa? port 0x1f88 bio irq 10 vector ncaintr #controller nca1 at isa? port 0x350 bio irq 5 vector ncaintr #controller sea0 at isa? bio irq 5 iomem 0xc8000 iosiz 0x2000 vector seaintr controller scbus0 device sd0 device st0 device cd0 #Only need one of these, the code dynamically grows #device wt0 at isa? port 0x300 bio irq 5 drq 1 vector wtintr #device mcd0 at isa? port 0x300 bio irq 10 vector mcdintr #device mcd1 at isa? port 0x340 bio irq 11 vector mcdintr #controller matcd0 at isa? port ? bio #device scd0 at isa? port 0x230 bio # syscons is the default console driver, resembling an SCO console device sc0 at isa? port "IO_KBD" tty irq 1 vector scintr # Enable this and PCVT_FREEBSD for pcvt vt220 compatible console driver #device vt0 at isa? port "IO_KBD" tty irq 1 vector pcrint #options "PCVT_FREEBSD=210" # pcvt running on FreeBSD 2.1 options XSERVER # include code for XFree86 device npx0 at isa? port "IO_NPX" irq 13 vector npxintr # option that serial port is a multiport card options "COM_MULTIPORT" # The native ports on the motherboard # com1 is used for the mouse so turn on diagnostics and turn off FIFO # com2 is used for the PPP line out to the ISP so Optimize it device sio0 at isa? port "IO_COM1" tty flags 0x86 irq 4 vector siointr device sio1 at isa? port "IO_COM2" tty flags 0x8c irq 3 vector siointr #the boca 8 port board ports device sio2 at isa? port 0x220 tty flags 0x78d device sio3 at isa? port 0x228 tty flags 0x78d device sio4 at isa? port 0x240 tty flags 0x78d device sio5 at isa? port 0x248 tty flags 0x78d device sio6 at isa? port 0x260 tty flags 0x78d device sio7 at isa? port 0x268 tty flags 0x78d irq 5 vector siointr device lpt0 at isa? port? tty irq 7 vector lptintr device lpt1 at isa? port? tty device lpt2 at isa? port? tty # Order is important here due to intrusive probes, do *not* alphabetize # this list of network interfaces until the probes have been fixed. # Right now it appears that the ie0 must be probed before ep0.
