@candy12 maybe can you explain the problem "after 8pm slowdown", cos it seem both Allo and U××f× having tis problem?

There are some new generation ISPs out there who are game changers in the industry would take the extra step in to add value to their subscription plans over others.
What they do is that they have a pro-active team which monitors their peak bandwidth utilization charts on their servers daily to specific popular streaming/gaming content sites and then they'd ensure that their wholesale bandwidth/upstream they subscribe provides 2-3 times the amount of peak bandwidth being consumed during the most busiest hours of the day.Also they'd pay royalties and exclusive rights to peer with the partner content network if they need to.
Take for example if their team notices that at the most peak hour (8pm-1am) Netflix server bandwidth consumption is about 25-30Gbps, it would make sense to subscribe an upstream connection to that particular ISP network which hosts Netflix server CDNs at 100Gbps. That way they can assure their customers that despite even at the most peak hours, they shouldn't worry because even so their access to Netflix servers won't saturate/slowdown because they've ample bandwidth to spare.
However there are also some lazy ISPs who doesn't care or have the initiative to make this effort. They'd just provide say 100Gbps links to certain popular networks and continue to oversell that bandwidth to x number of growing subscribers and be settled with it. Even if the access slows down or crawl during peak hours because too many subscribers are accessing the site, they'd just train their customer support to remind customers that their consumer service is on a "best effort" shared service. There's little they can do except to tell their customer off by saying why not try accessing the site during off peak hours.
In regards to these factors, there are few other factors which are beyond the control of your ISP:
1) Access to lesser known and less popular general sites hosted far away in other regionsSome sites and contents which are hosted overseas in other regions have restricted port speeds assigned to their shared servers.In such cases, even if you've a 10Gbps line at home do not expect miracles if the VPN server/content hosting server at the other end is only restricted to a 1Gbps port shared by a few users through virtualization.
2) Your internet service provider(RSP) sells their service over a wholesale national network competing with other ISPsThere's a REASON why some ISPs refused to join wholesale networks and become partner RSPs. They rather have FULL control and ownership from the gateways right down to the last mile access. It's not just about the competitive pricing structure without needing to consider other partner RSPs, they can also manage their bandwidth with better sight, planning and mitigations.
You know that each GPON port can provide upto about 2.4Gbps down/ 1.2Gbps upload speeds without considering TCP overheads yet. Each port is then shared upto 32 users max. Among these 32 CPEs connected to each port, you have telco U, A, M, D, C and V selling plans to their own customers who subscribe to various plans of different speeds. So if every user gets online and starts using their lines heavily during the end of the day after dinner, none of the partner ISPs can predict properly the wholesale network's peak bandwidth utilization patterns unless they have FULL CONTROL over it.
