    lan speed under 3mb/s

    It is a network 100mb/s
    The network has 2 wireless routers and 2 PC's, one ubuntu, one windows 7. Both PC have gigabyte type lan cards, however routers are standard 100 ethernet.

    Transfer speed seems slow, what do you get?

    Is this normal?

    If there is a great deal of tiny files, it can seriously hamper transfer speed. I'll bet you get much better speeds with a single archive (if only as a test).

    Yes, it looks like he has over 9,000 file left and he was halfway so he must be transferring over 18,000 files. It would be much faster with one archive file. From the looks of it I think they are photos so the size would be more then a text file.

    EDIT: I forgot to mention, back when I used Windows I noticed that Windows transfers files slower then Linux. There was a big difference in speed as I remember.

    If you are going to compress your files, this looked interesting. That is if they are .jpg files.

    Lots of picture files

    Compressing into a single archive speeds up a transfer?

    Well it's usually a toss-up between the time required to archive, send, and extract - and just sending all of the files.

    Re: lan speed under 3mb/s

    That looks about right for a transfer of thousands of small files.

    You must also recognise the difference between bits (b) and bytes (B). Network transfer speeds are usually quoted in bits whereas file sizes are usually quoted in bytes. As there are 8 bits in a byte the absolute maximum theoretical speed on a 100Mb/s network is 100 / 8 = 12.5MB/s. If you take into account the error checking and protocol overhead then you are looking at a maximum speed of around 10MB/s.

    As others have mentioned to get the best performance you would need to put all of your files in a single archive, doing this would get you closer to the 10MB/s mark.

    Maybe one more thing to mention. Router speeds. I have a linksys router and am replacing it today with a Asus router. My new router will be a 1 x Gigabit WAN port router. This will really improve my lan speed.

    Not really.

    The only situation where this will improve your LAN speed is if you have a file server connected to the single 1000Mb/s port and you are doing simultaneous transfers from several hosts that are plugged into the 100Mb/s ports. You will get no increase in your WAN speed or your transfer speed from single host to single host. Transfer speeds are always limited to the transfer rate of the slowest host.

    Yes you are right. Speeds are are as fast as the slowest port. My new router supports Ethernet and 802.3 with max. bit rate 10/100/1000 Mbps. So if I am coming off a 1000 Mbps port and going to a 10 or 100 Mbps port it will only run at 10 or 100 Mbps.
