To all Gurus,
Got some experiment going this morning on the 4Mbps ADSL line from Streamyx
First, I measure the max DL speed, by dl GB-size files from
http://oss.mmu.edu.my/pub/ubuntu-releases/13.04/I got about 450KBps DL, not bad
The second stage of experiment:
While the DL was still going on, I tambah an UL (a little 5 MB file) to my remote server
Suddenly the 450KBps DL speed tanked, to less than 100KBps speed !
And the UL speed was hovering in between 36 to 45 KBps
Why that much effect on the DL portion of the pipe when a little UL was commencing ?
I stopped all the UL and DL, then powered up a utility "Traffic shaper XP" ( from
http://bandwidthcontroller.com/trafficShaperXp.html )
Restarted the DL and the UL, and while both were going on, I tuned the "queue size" for both the UL and the DL, as well as the "speed limit"
After some observation, I set the "queue size" for UL to 23, and for DL, I put it to the max, to 100
I also prioritize the "acknowledgement packets" for both UL and DL, and put the rule "1" to DL, while for UL, I put it on the last place "9"
But no matter what I do, I can't seem to find a way to maximize the ADSL line's throughput
The best I can get is about an average of 44.8KBps UL speed and an average 280KBps DL speed
Is there any other measure, and/or any other utility that I can adapt to increase the ADSL line throughput ?
