wb fill incredibly slow

[Saelman]

Hi, im trying to generate a 20kX20k area using fill, and currently i cant get it to load anything over 100 chunks each time.
theres still plenty of ram left (6gigs), so im not throttling there.

[18:34:10 INFO]: [WorldBorder] [Fill] 18 more chunks processed (142596 total, ~8.7%) (free mem: 6257 MB)

Running Paper Spigot in 1.15.2

this is pretty much the constant rate of loading.
if you need any other info, i can totally submit that, just not sure what all you need for this.

@Saelman this is because the worldborder requests chunk unloads too prevent the server from running quickly out of memory this causes the slowdown if you want faster world generation with the cost of more memory usage you should use an fork of worldborder where this is fixed i can give you an build or you can build it yourself with intellij if you want. the issues linked is here #173

@TheCompieter @Puremin0rez Where could I find a compiled version of this fix?

@TheCompieter Sadly, this issue didn't fix my memory leak.

@edwerd try latest release that includes the fix for unloading chunks when memory is low.
