Subject: [PATCH] Optimize Chunk Saving Memory Allocation and Compression
|
|
|
|
Minecraft ineffeciently uses OutputStreams by calling .write(int) on the stream.
|
|
For Chunks, this is a DeflaterOutputStream, which allocates a single byte EVERY write.
|
|
|
|
This is causing the server to allocate tons of new byte[1] objects.
|
|
Additionally, this is very ineffecient for the Deflate process.
|
|
|
|
By Buffering Writes the same way it already is Buffering Reads, we will
|
|
write to the stream much more effeciently.
