comment IpTables -j REJECT to instantly block the loading on user browser
@emirjonb your approach fails for some reason. But there is a chance to find out why, which is: methodical troubleshooting. This is how you do it: compare the expected outcome with the actual outcome on every level. Wireshark is a great tool for doing that.

First understand how ip, tcp, and iptables work. Then if you still want to use iptables, analyze this with wireshark.

comment find command locking the system out
Okay, but anyway, what makes you think, find somehow goes over the whole inode data? In what sense, anyway? After all it's the kernels job to do that, and it does it anyway, even when ls is successively readdir()-ing the directory. So honestly, it is not at all clear what "going through the inode metadata" even means.

Besides that, even a couple of Million bytes of inode processing barely explain a weeks worth of computation.

comment find command locking the system out
I don't think so. I've just skimmed over the gnu find and ls sources, and it basically does the same as ls does: opendir() followed by readdir() (see function xsavedir() in savedirinfo.c)

This still doesn't explain why find is slower than ls
