pre-load world for less lag

My server has a open world, because of that a lot of chunks are being loaded by players flying around with jetpacks and such.

The lag is being caused by the world saving automatically whenever new chunks are being loaded.
Is there a plugin out there that pre-loads certain chunks in a world to prevent lag?
Or is there anyone that can help me with this?

Thanks in advance,
Retourned


NEW:
Plugin category: world

Minecraft version: 1.8.8

Suggested name: PreLoadWorld

What I want: This plugin needs to be able to keep certain chunks loaded inside a certain world so theres less lag being caused by people going around in an open world.

 

You are asking for a rather huge performance hitter,while yes flying and loading unloading chunks its meh,its much better than keeping all chunks in memory destroying ur server

The chunks beside themself also keep track of entities and such so loading all the chunks at once will mean also loading everything else with it,you should just look into some faster chunk loading/unloading plugin

 

There are a lot of plugins like this.
Overview - UHC Chunk Preloader - Bukkit Plugins - Projects - Bukkit
Overview - WorldLoad - Bukkit Plugins - Projects - Bukkit
https://dev.bukkit.org/bukkit-plugins/maploader
And even more on Spigot.

 

You can also try to use the plugin WorldBorder. When you set a border you can pre-fill the whole area server-sided so it won't take as much load. It does take a bit of space on your harddrive.

 

So many things to think about before generating a world...Seed? Etc, etc, etc!
WorldBorder FTW. <3 Best generation operation for a reduced lag world?

Whitelist server. Remove all plugins not required for world generation.
Giant Trees, Giant Caves, Custom terrain/ores, Custom schematics etc?
Dynmap while rendering also? U Crazy? I was... It took my hosted
20gb ram server 2.5 days to render 12500x12500 radius massive terrain
customisation. 100+ block high trees, loads (100s 1000s small schematics
ExoticGarden + CustomStructures tree/ore schematics)
Server had 7-10 TPS for the full 2.5 days and Dynmap took
more than another whole day to catch up with the tile queue
Done. Ty WorldBorder. Got ALL the lag bully stuff done.
All I did was /wb survival fill 20 125 true

With masses of chunk customisation and laggy giant trees/shadow updates etc?
/gamerule randomtickspeed 300 before you generate so plants get a growth
boost to age your world as chunks load and despawn invalid leaf blocks also?
Get Clearlag to wipe all items (NOT villagers, chest_minecrats etc lol. SAFE config.yml first)
every 2 yes 2 seconds for the entire time. This removes 1000s of entities
like dropped saplings, blocks, items on the ground. Removes lag for
those items before the chunk unloads so when a player arrives later there are none there.
Make sure to look at spigot/paper chunk lighting updates cache so all lighting updates are not skipped.
WorldGuard make sure zombies do not attack villagers while you load and render chunks.
Fire spread is off etc. Now U maybe ready to flood fill out your existing world.

Think first before you /wb survival fill 20 125 true
(true forces chunk to load + all chunk updates to get done. 20 is the chunks per tick
loaded and saved which is slow. 60 is fine with no custom terrain etc. 125 is the amount
of blocks outside the border generated for visual effect.) Using false instead of true can
result in poorly generated chunks. No lighting updates or other glitchy stuff but will
cause WorldBorder to skip all chunks already saved. Avoid false if I were you.
You can do it very slowly and not hurt your TPS. Done at non peak player times
nobody would notice you even did it without havng to strip plugins and /whitelist on.
