I haven't experienced blocklag(the lag you are referencing) in a very long time, months at that.
I'm not trying to jump in and say "your idea is stupid", I'm simply adding to the aforementioned narrative that the latency issue is on your end.
If I'm not mistaken, the MC 1.8 update made obfuscators(the anti-ore finder plugin) completely useless as only visible geometry/blocks are handled by the client's side, or something along those lines.
Not to mention obfuscators wouldn't have ever effected a cave finder plugin anyhow.
-1 but +1 if my hypothesis of the obfuscator plugin is correct.
The obfuscator need not be running if it is no longer helping.
@@Fuzzlr or anyone else got a better answer on that^?
