General FTP question (4 posts)

    I am not an expert but I have a feeling that my (Speedtouch 510) ASDL modem is slower than it is supposed to be.
    My ISP tells me my ASDL line is OK and should do "3300/512".
    However, when using Fetch for uploading it mentions speeds varying bewtween 16 and 18Kb/s.
    How does that relate to the "512" claim?

    The 512 refers to kilobits per second. When Fetch says 18KB/s it means kilobytes per second. There are 8 bits in a byte, so your Fetch uploads are going about 144 kilobits/second. That's less than a third of the line's advertised speed, so I'd recommend complaining to the ISP.

    Thanks,

    An additional question. Do you know of a way to test whether anything on my Mac (anything but Fetch) limits my uploading speed. Not being an expert, I read a lot about Firewalls that block uploads, ports that should be open etc.

    Firewalls typically block ports 100% or not at all. So a firewall problem would result in failed transfers, rather than slow transfers. You can check whether the Mac OS X firewall is turned on by choosing System Preferences... from the Apple menu, then clicking on the Sharing icon, then on the Firewall tab.

    You can test your connection with speed tests such as the ones at [url]http://www.dslreports.com/stest[url] Try multiple tests to get a more reliable indication of your connection's speed.

    Thanks,
