Hey, is there any actual plugin which can do this? For example set corpse despawn to like 5-10 sec? I found only that you can set despawn timer for the bag that drops with your items after death, but I find that with many dead bodies at one place (let's say 200 players at one medium radius) are making the game lagg and server too. Is it event preventable, or 200 players is already too much to handle for the server and client?

It's available as a native console command:

server.corpsedespawn X

Change X to a number.

how do you get 200 players to even die at the same location?
