What does it mean when upload speed is faster than dl speed?

post #1 of 11
Thread Starter 
This is from my PC at work. The internet connection has been really, really slow for the past few weeks (ever since our IT company changed some things) The problem we have is, once we tell them that it is slow and it is most likely due to something they did (or didn't) do, they usually reply that is us or something we do that is causing it. I don't kow much about networking and the people responsible for hiring them and paying them know much, much less.

My question is, what would cause ping times and DL speeds this bad? I don't think I have ever seen DL speeds that much faster than upload speeds. They do use an IP blocker (sonic wall) to filter bad sights (even though it filters tons of sites for no reason) I believe we have a T1 line for our building and it is networked between15-17 machines. I know that some people us internet radio and other things like that, but this is almost unusable. I am trying to see what I can figure out before I contact them again. (our IT company)

that's pretty sad. i usually get 2-3+ mb/s DL, with 700+ mb/s upload... at my high school our wired/wireless connection is usually around 54mb/s, which is crazy!

If upload is faster than download, the most logical reason would be that some of the download bandwidth is being used.

But to drop a T1 connection down to something lower than a 56k modem? That is either a VERY bad server you have or they are complete @(#*$@(#$. Try hooking a computer directly up to the T1 line during off-hours or something and see what you get. It could also be that the IP blocker is screwing up the test.

Wow! Can you even get onto a website with that? It would take forever.


Hm, I'm not very knowledgable about networks either and I don't understand this:

Well I see that my speed is 100 Mbps, through my local area connection status. Is that wrong? Because I don't believe I have a fast internet connection. Unless the 100Mbps is really 100 megabits per second. Which would mean that my speed is 12.5 megabytes per second? Wait a second....that can't be right can it?

100 MB per second is your cable if I'm not mistaken. Cat5e cable has transfer rates up to 100MB/s

Go to www.speedtest.net to find out your real speed.

1) a T1 is only 1.5\\1.5mbps. Divide that across 17 work stations and you come out with 90kbps per workstation if everyone was fully using the internet. Clearly the QOS for the network is setup to allow a single user to pull down extra bandwidth when it's available.

2) DL is use MUCH more than UL. In a typical office the applications a user would use run at a 10-1 ration of DL vs UL. Since you have a original UL and DL of the same value, getting lower results on DL doing a speed test is to be expected.

3) the reason you run slower is mostly likely QOS. Most likely the QOS for your server simply balanced use across active users. This mean that if you're the only one using internet you can run at max speed, if someone else was using you coudl only run at max - whatever they're using. IT probably changed it so that you have a maximum usage to prevent network drag by a single user trying to use too many applications that DL (such as internet radio).

4) your network appears to be running fine. IT has probably thorrtled down how much speed a single user can pull down at one time, thus making usage "fairer", and reduce a single user pushing up latency.

Go to www.speedtest.net to find out your real speed.
Since the maximum DL speed for a home ISP is around 50Mbps (FiOS), and businesses using routers and QOS to limit speed for users, you're not being slowed down by your cable, which can handle 100Mbps.

OK, update: It appears we have a fractional T1. Our IT company claims that the max DL speed is 384 Kb/s. It appears that 2 people were using internet radio and they claim that is what is hogging all the bandwidth.

As far as the work stations, only 10 or so are every active at one time. I am not sure what "fractional" refers too. It seems a bit better once I shut down the radio users. The IT guy I spoke with mentioned throttling, but it isn't being done now and we agreed that there isn't much there to throttle anyways. I think we are getting shafted by both my company (for what they will pay for regarding IT service and ISP service) and the IT company (knowing this place, the cheapest guys around)

Most businesses have better internet..even my bandwidth is ~1800kbps/1100
at home in Oklahoma.
QoS is a definite possibility, but your bandwidth still stinks.

Fractional T1 is basically your not getting the FULL T1 that way they can make it more cost effective for small business's etc. i believe they go from 1.1Mbps - 512k - 384k - 256 - 128k - 64K and to be honest your speeds look about on the mark especially if QoS is enabled...
