@fruitie and other 30M users

I tag Fruitie is because I only remember her XDD

Okay, I think I might have explanation/answer for why we as 30M user are NOT getting full 30M of speed nowadays.

From my opinion, TM cares about bufferbloat (or simply just want to save bandwidth?)

Bufferbloat means high latency when a network buffering too much of data (at peak of the speed)

Where you can notice ur skype (VOIP) is not stable, ping (gaming) becomes higher or browsing page seems slow responds when someone downloading/uploading at full speed.

In short,

Bufferbloat = high ping when downloading/uploading at ISP provided full speed

Solution,

Limit the peak download/uploading speed

For example, 30Mbps will be > 28Mbps

That's it, limiting speed.

And yes, speed scarifies but it gives you a more smoother network.

Back to topic,

now TM limiting 30M > 28M, and suprisingly when we do a bufferbloat speed test, my bufferbloat for downloading is good (low), which means bufferbloat solution is applied here.



Which also means TM is not limiting our speed in a FIXED value?

If fixed 28M, then if I do bufferbloat speed test, I will get higher ping while downloading.

for example (but this is while uploading la)



What I actually means is TM maybe is doing bufferbloat setting in their side (for downloading only)



The end.

Just sharing how SQM works.

SQM tuned OFF

SQM turned ON

if you compare with the above one, both ping is low even when in full speed.
