uploading kills download speed

[cybershark]

Since the upgrade to 384 I noticed this.

I ftpd a 7mb file today at an average of 13.46 Kb.
While I was doing this my browsing was very slow, I looked at my traffic monitor and my download speed was averaging 5-7Kb.

When I was on 192 I was able to ftp@18Kb and download@20Kb at the same time.

Has anyone else noticed this?

yeah thats y i upgraded to a 1mb line. Couldnt stand the poor upload speeds.
I can multi task my 1mb line soooo nicely now its like heaven.

Jup, ive noticed the exact same thing here. Also noticed trying to run simultaneous downloads leads to really unstable speeds

 

[curiouswanderer]

hmmm..downloading torrents at 35-40kb/s and uploading at 10+ kb/s. U guys sure this happens? I havent noticed at all after the upgrade.

 

[Turbo_Aspiration]

Ur lucky then.. an upload just started and my download went from around 15kb/s to 3

512 lines upload at the same speed as 1mb lines right? According to Telkom - http://www.telkom.co.za/athome/products/dsl/home_which_dsl.html - both upload at 265 Kbps

when upload bandwidth is saturated, then downstream bandwidth is affected

too much to read on a sunday night, grab a coffee on monday morning and dive into it.

not sure why it didnt happen with the 192 package, but over the pond here that has always been the case...when uploading like mad (80%+ capacity) then my browsing goes to poo and even my downloads slow down quite a lot. the problem is compounded by the very asymmetric nature of the cable connections here...128k up and 4-10meg down (at least, that is what my provider offers)..ouch

512 is 256, and 1mb is 384.

That's your line speed that your modem syncs at. In all likelihood Telkom would have implemented a script which limits you to approx. 80% of 512k speeds

Telkom gives you a bit extra than what you payed for to handle the overhead of using PPPoE.

The Telkom website is talking lies...

Oh and btw i do upload at 384 speeds. Anywhere from a solid 38-46kb/s.

Anywhere from a solid 38-46kb/s.

How do you measure it ???.

 

[dabouncer]

I look at the speed and find the highest constant upload rate for like 1 hour or so.

Using ftp perhaps ... it tells you rather accurately the time it took and average throughput.

AFAIK speeds are limited at the dslam and differ from what your router reports - or are you downloading at 1152 also?

It's not much of a telkom lie if you're getting more than they say - thats called a bonus.

 

[Moederloos]

I have the same problem - if I upload a large file via FTP, download capability is shot.

What kind of router?
