Mojang made some changes to priorities in 1.17 and it seems that these changes conflict with the changes made in this patch, which in some cases appears to cause excessive rescheduling of tasks. This, however, is not confirmed as such but seems to be the behavior that we're seeing to cause this issue, if mojang has adopted the changes we suggested, then a good chunk of this patch may be unneeded, but, this needs a much better look than I'm currently able to do

Subject: [PATCH] Optimize Dynamic#get Missing Keys
|
|
|
|
get was calling toString() on every NBT object that was ever asked for an optional
|
|
key from the object to build a string for the error text.
|
|
|
|
When done on large NBT objects, this was using a ton of computation time building the
|
|
JSON representation of the NBT object.
|
|
|
|
Now we will just skip the value when 99.9999% of the time the text is never even printed.
