Needs to only dump x many at a time no matter what.
Does it lag from the act of dumping the 1000 ores, or from the 1000 ores on the ground?
Probably the act of dumping 1000 ores
I don't think a measly 1000 items just sitting around would lag the server
Or at least I hope not

Alt+click
I don't think alt click can save you from this.
Not from the server lag, but from what @Zth-- said
I personally use altclick, but newbies don't know it exists. That literally happened to me when I was learning the game
