Re: [RTnet-users] [RT-FireWire][Announce]0.1 release of RT-FireWire

400Mbits/s for rt-firewire and 100Mbits/second for rt-net, that's what I thought, but somebody had said that in reality they were getting slower communication.  I guess it does depend on the CPU and RAM, but isn't there some CPU (say 3ghz) and RAM (2GB) that would get 400Mb/s easily? Thanks and I look forward to doing some testing with rt-fw and ft-net, great effort, Ted On 12/2/2005 1:33 PM, Yuchen Zhang wrote: On 12/2/05, Ted Huntington <[EMAIL PROTECTED]> wrote: Can anybody say what speeds they are getting with RT-FireWire in terms of bits/second? I am interested in seeing what people are getting for RT-Net in terms of bits/second too. The physical speed really depends on the hardware. For RT-FireWire, currently we supports ohci1394a board, which supports up to 400 Mb/s. For RTnet I think also, the physical speed really only depends on the hardware you use: either 10/100M or Gigebit Ethernet board. BUT, personally I think the point to develop real-time network software is to get stable, deterministic transaction performance out of the promising characteristics of hardware part, like FireWire, compared with traditional fieldbus, e.g. CAN, profibus. The goal to increase physical speed limit can never be met by software. Best regards, Yuchen
