TL;DR: because unvetted nodes belong mostly to serious SNOs with serious networks.
with IP limit OFF, they suddenly joined and inflate the test result.
probbaly because only significant SNOs, who already have xx or xxx nodes vetted from long time, does incubate spare nodes, just in case. Those operators has serious equipment and networks, this, with combination of net /24 ip rule suspended, uncovered theirs network potential, and that great majority of unvetted is connected to good networks. And that, the only biggest players think about making new nodes, to secure theirs existing operation or to expand. If only as a spare nodes - then the question is why they worry? Not so easy to loose a node, You have to be offline 30 days. Sure, You run say: 200 nodes, and You loose some, You want to have spare nodes. But if You have 200 and You run 200 spare with minimal HDD space, i would question that. For me its proooobably because those xx or xxx or maybe xxxx nodes are run from same location, just on different ip.
Thats why they are so afraid if something happens, all nodes are cooked, so have to run a lot of spare as well. To me, it says that no new nodes from outsiders. i conclude pay rate isn’t encouraging. Not an offtopic, just Another argument for if You want more space to be added, and importantly, from new people, NEW ppl to join, maybe You could consider to share with us, SNOs a little bit more. if You face need of rapid growth, isn’t it better to think about it earlier? There, my stance sits still, a 2,5$/TB/storage is fair! And how wonderful! You can use results of this test to conclude how to adjust the reed solomon to meet the numbers, so everyone are happy! Long live the Storj!
so You just discovered most of unvetted nodes are spare parts for most serious SNOs, mostly with Online nodes circumventing Your net /24 rule. (or they couldn’t be doing this seriously) Now If You have a lot of Nodes with same IP, but small HDD, now, most likely You got real IP of those guys. Or at least main IP. Without VPN. No one sane would keep 10-20+ nodes on same IP, even 3-4 neighbors gives no gains, i got such 1 node, but i do nothing yet, but i will.
If You do xx-xxxx nodes = You do it for profit, and seriously. And You have to have 1 IP per 1 HDD or it makes no sense. Not sure if i want add more atm, tho i will play pangolin with “no surprise to me”. And in case what to change? idk depends if thats realy a problem, from throughput stance of course. Other than throughput i dont wanna start offtopic, and that’s where I’ll stop.
