I will stay through the attachment errors, 504s and 502s, such is my desire to sneed. Thanks.
 
COME ON OUT YOU RAPIST said:
They have two general threads, one for employed people and one for unemployed yet qualified people. I don't know what Null's budget is like. I don't know if consummate professionals would be willing to touch the evil doxing website. What I do know is /g/ still has some people posting who aren't retarded, in theory one should be competent enough to troubleshoot.

There is absolutely no way Null would trust anons from 4chan for this. Whether they could do it or not is irrelevant, sadly.

My post will reveal my total lack of tech knowledge, but I'm assuming from the way you say this that it's theoretically impossible to become schizophrenic like Terry and "build your own XenForo"? Or like a completely unrealistic amount of resources needed to attempt such a thing for the sake of a drama website.

In the works already, Null is spending his free time (what little he has when not strangling the retarded servers or users) rewriting the farms in Rust. It's slow going because nothing leaves him alone to let him work on it.
 
TFW some random inexplicable tech issue is doing more harm to the site than the concentrated efforts of the tranny cabal ever could

The Kiwi Farms is mostly one sever but also about 10 servers. Our topology has three layers:

1. Entry points. These are the IPs you connect to. They are simple TCP reverse proxies. I call them "zero-trust proxies". They know nothing. If they are compromised, even by the host, nothing happens.
2. KiwiFlare. This is a rental server in a datacenter I trust. It's only job is to run KiwiFlare and handle abuse from Tor and the Entry Points.
3. Kiwi Farms's general application server.

At risk of suggesting some troubleshooting you may have already tried, but have you ever ran iperf throughput tests from each of the entry points to the app server and also from the app server to the entry points? With everything being so slow, even tiny-ass ssh connections, it really reminds me of old issues with Virtual Machine Queues. Network switches will have a certain hard limit of how many VMQs it can support, and in many cases turning VMQ off entirely improves performance if the switching is trying to use VMQ but doesn't have enough to support it.

I could see a case where the entry points might be virtualized and flooding the switch VMQs, which would absolutely cause such slow-but-eventually-works issues as 10 second ssh typing. I don't know how many VMs I've had to disable VMQ on over the years so hopefully this is actionable for you and not another dead end.

Edit: KVM calls them Multiqueue, I guess VMQ is a Hyper-V name - but the tech is still used in general and can fuck shit up.

The full scope of the problem looks like this:
  • Typing in SSH takes multiple seconds.
  • Connecting via SSH takes 10+ seconds.
  • Requests to the Kiwi Farms take multiple seconds even for rudimentary requests.
  • Everything is FUCKING SLOW.
  • This problem is INTERMITTENT. Sometimes the site loads instantly.

Is SSH still horribly slow even when the server has just booted without any of the KF services running? And when you say that the problem is intermittent, does that include SSH? Or is SSH always shit?
 
You mention that ssh and such is slow have you tinkered at all with the tcp kernel parameters in the past that might have gotten lost/not written to a config file on the reboot for the RAM upgrade?

I'm not sure what kind of telemetry you have on performance but you would have to look at counters or load something like https://github.com/netdata/netdata and start collecting some data to look for anomalies.

I have no technical knowledge or bad jokes to make, just wish you the best at fixing this shit.

If I have to wait 30 seconds for every forum page to load for much longer I'm going to lose it.
 
The only problems I come across are with videos, sometimes they load, sometimes they take fucking forever. Other than that the site has been fine.
