A 1Gbps connection should be around 1024Mbps If i am not mistaken (please feel free to correct me if i am wrong) but usually most people get around 940 - 960Mbps.... what happens to the remaining 40 -50Mbps. On a 100/100 connection, i used to get 105mbps download and 105mbps upload but on a Gigabit connection i get max of 960Mbps. whats going on? I see most people also get around the same speeds.

Question of the Day: Have you ever been to an airshow?
Silly question. Any thoughts?

I think that's more like a theoretical 'up to' speed, achievable when all the elements align, especially on a GPON network.
Alright, that's an excellent point. So lower speeds are more likely to hit their max speeds than higher speeds right?
The port speed is the bottleneck. To get more than 1Gbps you would need to have 10Gbps ports on all the devices like the PC, Router and ONT or CPE.

yeap... the higher the expectations, the easier to hit bottlenecks along the way.
Hence, it could even be a cpu or ram limitation on the router and/or your computer theoretically.
Like I said, everything needs to be perfectly aligned.
Have you tried a speedtest at like 3 or 4am in the morning?
I remember with my 100mbps line back in 2013 in Seoul, Korea, at 7pm it would drop to around 20mbps, when everyone is on it, but at 7am it would also be 99 - 101mbps. More recently there's much less congestion I think as they upgraded their pipes.
My Pc has a 10gb Lan card. I am not sure about the Microtik router though lol if it has a 10Gb port.

This is called overhead. A number of bytes on each Gigabit transmitted frame is used purely for protocol related things such as Ethernet, IP, and then TCP, which equates to around 5% overhead on a Gigabit line, which then amounts to around 50mbps "lost".

That would make sense if you only got 95Mb on a 100Mb line, but in most cases you get over 100Mbs. Unless a 100Mb line is actually a 110Mb line to give it some headroom for TCP overheads.
That is indeed true but remember the port speed is 1Gbps then so there is plenty of headroom. Change the port speed to 100Mbps and see you will be capped at around 93Mbps.
I have ruled out the pc so far but i will do the speed test and see which is which. I am the only one using the 1Gbs connection so there goes sharing heheh.
When I had a 100meg line, I got a consistent 105megs up and down. how does that work? Why is the same not true for higher speeds? When Vumatel upgraded us to that promotional. double speeds I got a consistent 206/211 up and download speeds. Now on a 1Gbps connection, I get from 936 - 960Mbps. Never a full 1024Mbps. Do you think a Lawsuit is in order? lol
As mentioned the port speed is the bottleneck currently. When you were on 100Mbps and 200Mbps the FNO speed capped the connection and all the port speeds were at 1Gbps.
If you take a 100Mbps fibre connection and connect a CAT5 cable to the ONT is will negotiate 100Mbps only and the speed cap will be ~93Mbps because then the port speed is the bottleneck. Now swap the CAT5 for a CAT5e or higher cable the port speed changes to 1Gbps and now you get ~110Mbps because the speed cap is now applied by the FNO.

Many providers actually "overprovision" 100/200Mbps lines a little "above" the advertised speed to cater for the overheads, so that clients do not complain. The rate-limit on the switch or GPON head-end is normally around 110Mbps or 220Mbps.
When it comes to gigabit services, there isn't a chance to overprovision by the extra 5% since all current FNO networks, Active Ethernet, or GPON are limited to 1Gbps physical speeds.
If you had a gigabit lan switch in your home, and a speedtest server on the same switch you would never see 1000megs, you would see around 950.

This exactly, see my prior post.
Oh that makes a lot of sense. I tried everything and max i get is 960Megs. Usually it is around 9360 - 950megs consistently.. So i guess for Gigabit connection, this is as good as it gets. No wiggle room for higher speeds right?
Hahahahahahahahah that is so funny lol omg. You made my day man lol hahaha

Fibre like ADSL is Best effort.
I am looking for an alternative ISP to WebAfrica
@PBCool as mentioned he called me not the otherway around yesterday evening. It was tough luck and Cool Ideas want to terminate immediately. Additionally CPE was swapped out and 2 brand new routers tested ( I bought a brand new Tp link C80 and you guys sent one), yet the problem persits. So is...

Absolutely no wiggle room, unfortunately. The line can only operate at a maximum of 1Gbps, not 1050Mbps, so the overhead will always be the 5% which gets you to 950-960. Then, we need to talk about retransmissions occasional packet loss etc, which could also reduce the eventual throughput.
Oh alright that explains a lot. So i guess this is the highest i can get with current network speeds. Unless i opt for business fibre. Does business fibre offer higher speeds like 10Gbps?not that i would consider getting it though 1Gbps is plenty fast for me.
