Messages are now identified by their string contents, and not their Text instance, meaning that the mod should be faster in general - but this may not be that obvious.

We have added a cache to Minecraft’s code which splits a single text message into multiple lines to be displayed, this was an expensive operation, and if it was being run for the same message multiple times (which is the case with Compact Chat, but not in vanilla, due to us removing duplicate messages), it will cause a lot of lag. This cache’s entries are cleared if the entry has not been accessed for over a minute.
