here is my speed result after optimization. nothing changes i think..

[mccoffee]

that's probably as good as it gets then

[eirhon]

does it mean, my ISP is limiting my internet speed?

[dlsayremn]

No. Because of line electrical resistance and other issues your actual speed will always be about 80% - 90 % of your allocated speed.

[eirhon]

is there anything i can do about this?
the odd thing is, before i was able to get 900 kbps - 1mbps speed.
but now i only get a max of 860kbps.

change the mtu to 1500 I had typeo
