If you have a 10GBaseT connection, only using 5Gb in one direction doesn’t give you 15Gb in the other. It’s still 10Gb either way.
That's just a question of adhering to standards. The chip that does the routing internally has a total throughput and that is obviously both directions combined.
A factor I noticed here with my fiber ISP that hasn't been mentioned: total bandwidth of the router that comes with the contract.
While this is finally changing now, the cheap SoCs that where used for building these mass produced routers topped out at about 1.5gbit total throughput.
So to avoid people complaining about false advertisement and still sell ”1gbit" fiber, the maximum they are offering is a 1000/400 Mbit connection.
Cool stuff.
Is it possible to set both a dark and a light theme as a default?
Yes, this is a good observation, but the question is what is really the cause of this? Clearly it isn't economics alone. I would guess it is mostly due to specific family dynamics and this wouldn't necessarily extend to non-biological extended "families" of your choosing.
Well, that's good, but a lot of trust was lost in the mean time and I doubt I'll go back using it.
Somewhat surprising that it seems that profitable and that they already have enough funds to build a second one.
It's likely Cloudflare related. Some of the larger instances are behind that, but many of the smaller ones aren't. Cloudflare isn't only a problem for VPN users, so its a good idea to avoid those instances as a user. You can still interact with their communities via Federation.
Wordpress is a pile of decades old php code* that is held together with string and tape pretty much.
*php isn't the problem itself, modern php is actually pretty nice.
Given how crufty Wordpress is, I don't even dare to imagine how bad the Tumblr backend must be that this is seen as an improvement by the developers.
No, they found some billionaires to do it 😉
The routing equipment at the distribution boxes is likely a limit. Both in regards to power consumption and heat production, plus especially with older equipment the total throughput it is capable of.
