I wanted to share my experience with the MR 10Gbps Plan (standard plan, not the gamer plan) after using it for a month now.
1) Initial installation: issues directly after installation - disconnected every 15-20 seconds. Jumped through a lot of hoops on my end after speaking with MR support (change cables, changed the SFP modules, reset router, etc etc....). At the end, it turned out that the Nokia ONT provided was faulty. MR replaced it 3 days later, and since then, the connection has been stable.
2) Speed:
1 week of hourly speed tests showed the following download and upload speeds.
Download is good and is quite stable (some hick-ups here and there) with an average speed of 6.5Gbps
Upload is a different matter and fluctuates a lot depending on the hour of the day/quite random. Average speed comes in at 3.3Gbps.
Note: Speedtest is done with a 10Gbps wired PC behind the Router/Firewall -> realistic throughput on the LAN I can get between router and PC is 7+Gbps. So the network is not limiting the results.
Important: Speedtest always connects to local Singapore servers -> real use to overseas servers/pages etc will give a very different experience, of course.
In summary, quite happy with it so far, now that it is stable.
Is 10Gbps needed even when you have the infrastructure at home to support it?
No, not a real difference in experience for my day-to-day use from the previous 1Gbps plan I was on (limiting factor is the international connection and the receiving server anyway)
