CraftBukkit added synchronization to read and write methods. This adds much more contention on this object for accessing region files, as the entire read and write of NBT data is now a blocking operation. This causes issues when something then simply needs to check if a chunk exists on the main thread, causing a block... However, this synchronization was unnecessary, because there is already enough synchronization done to keep things safe 1) Obtaining a Region File: Those methods are still static synchronized. Meaning we can safely obtain a Region File concurrently. 2) RegionFile data access: Methods reading and manipulating data from a region file are also marked synchronized, ensuring that no 2 processes are reading or writing data at the same time. 3) Checking a region file for chunkExists: getOffset is also synchronized ensuring that even if a chunk is currently being written, it will be safe. By removing these synchronizations, we reduce the locking to only when data is being write or read. GZIP compression and NBT Buffer creation will no longer be part of the synchronized context, reducing lock times. Ultimately: This brings us back to Vanilla, which has had no indication of region file loss. Closes #1260 |
