Thanks for the things you do, the bandwidth problem is a frustrating one and after discussing it with timcliff we still do not have an answer about the way it is being calculated and and more importantly - what is the restoration rate of it? This is a crucial point as it blocks a user from doing anything, happened to me and it was annoying as hell.
Will be happy to get an answer if you know or can dig into the c++ involved with that issue.
I think I will upvote you - your server looks impressive.
The bandwidth is a fractional reserve. Basically (simplified): The steem network has an amount of bandwidth available and gaves you some of that, respective to your steem power. You can use that bandwidth. But if people use the bandwidth, there is less available, so steem will give less out.
Example: Say I have one GB available. And I do a huge post that cost me 3 MB. That post reduces the network overall supply and I have used 3MB of 500MB. If I do another post, I have used 6MB of 250 MB. And if I wait a bit, the network has less load again and I have 6MB of 1GB again.
So: How much bandwidth actions cost, that is pretty fixed. But how much is available in the system is always in flux. Similar to how voting power is pretty easy to calculate, but determining how much your upvote is worth is pretty complex and changes all the time.
So while timcliff and many others know how it works, explaining it is not easy. And since the maximum is system dependent, there is no easy way to show it per user.
I am also experiencing the bandwidth problem 4-5 days.And I don't know what the cause is.You said related to what we do on the site.but I did not do any operation for 15 hours, compared with the bandwidth error of the band.So I did not fully understand why ?
Thanks for information. @reggaemuffin
