Gregory, I have a few observations, rather than an answer to your question. Make sure everyone is clear about the units of measurement you are reporting. Often there is confusion over kilobytes per second and kilobits per second. Windows applications often report in kilobytes per second. Often you can not rely on the way they capitalize the abbreviations for kilobits and kilobytes. This can lead to speeds looking like they are off by a factor of ten or so. There doesn't appear to be anything in your hardware that should limit your speed, other than your ADSL cap. My router/firewall based on a 486DX100 with 10 Mbps ISA cards and running the 2.4.xx kernel, seems to easily handle my 3 Mbps cable modem connection. The speed test sites vary wildly in the numbers that they report. Your bits are traversing a path that you have little control over, so there can be any number of bottlenecks between your server and the test server. You will get the most consistent and accurate results if you can transfer a large file between one of your ISP's servers (hopefully located nearby, with few hops) and your server. If you are running PPPoE, that can have pretty severe overhead, from what I have read. -----Original Message----- From: speakup-bounces@xxxxxxxxxxxxxx [mailto:speakup-bounces at braille.uwo.ca] On Behalf Of Gregory Nowak Sent: Saturday, June 19, 2004 5:08 PM To: speakup at braille.uwo.ca Subject: speed question -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all. I've been wondering about this for a while now, and thought I'd get some input on it. I'm on a ADSL connection, and my downstream speed is supposed to be 1536 KbpS, and my upstream is supposed to be 128 KbpS. My network setup is as follows. The ADSL modem is connected to my server which is a pIII 600 MHz, with 384 Mb of ram. Other machines on my LAN have access to the internet via iptables on the server. My second ethernet interface on the server is connected to a 100 MbpS switch, which all the other boxes are connected to. All the network cards in all my boxes are 100 MbpS. I've noticed that when downloading things with lynx the cat on my server, the highest download speed I ever got was 170 Kbps, the lowest was about 20 KbpS, but on average, download speeds are about 150 KbPs. Thinking that the speed should be higher, I ran a speed test at dslspeedtest.com using my windblows box (the test didn't work with lynx/links), with the windblows box connection going through the switch, which is connected to the server machine. The test told me that my speed is about 700 KbpS. I then plugged the ADSL modem directly into the windblows box, made sure my ie cache was cleaned out, and tried the test again. This time around, I was told my speed was 1 MbpS. My question is, with the downstream speed I mentioned earlier, should I be able to get downloads on the machine connected to the ADSL modem at 170 KbpS max, or should they be higher then that? Thanks.
