For some reason, after launching a tier 1 HE missile, server started lagging really badly, but before everything worked perfectly

98% of your CPU time are being consumed by EntityArrow which I don't think has a whole lot to do with any missiles. Maybe someone spammed one of those ancient frag grenades which spawn arrows?

I dont think so, because the lag starts immediately after i launch a missile

Well sure but that doesn't automatically imply causation, profiler says that the lag comes from arrows, and missiles neither use nor spawn those, so that seems to be unrelated.

Is there any way to kill every entity on the server in 1.7.10?

On a vanilla server? No, but I think Essentials has a command for that, assuming you have that plugin.

Well, I'll see what I can do about that. Thanks for help

Yeah, I fixed the problem by just deleting the region that contained 8000 arrows (bruh), but I still find it weird that the lag only starts when launching a missile

Missiles chunkload, it might have been the missile just loaded the chunk with 8k arrows which led to lag.
