When using Creative mode, bridging and tunnelling is excruciatingly slow over large distances.

Describe the solution you'd like
A setting inside "Options" that allows one to adjust the speed at which tunnelling and bridging happens.

First,this speed looks like restricted by CPU speed?My CPU is i5-8300H,this speed very fast,then I was in a server,the building speed is slow(this server's CPU is E5 2696 v2).so I think this speed Equipment related or.

Looking into it further, it does indeed seem that bridging is faster at some points than others, indicating that this is probably an issue with my computer's performance - I'm running an Intel Core i7 8th gen, but with no dedicated GPU. I might be better off using WorldEdit in the future for this then.

but some WorldEdit script need 1 block width lines,so I think this mod need a 1 block width bridge building?
