首先前面我们已经分析过了,在内存频繁使用的场景中,内存池 PoolArena 中的 PoolChunks 大概率会集中停留在 q050 和 q075 这两个 PoolChunkList 中。由于 q050 和 q075 中集中了大量的 PoolChunks,所以我们肯定会先从这两个 PoolChunkList 查找,一下子就能找到一个 PoolChunk,保证了第三点原则 —— 内存分配的...
By default, this option was enabled in the previous releases, and verification was split into two phases: type referencing (performed by the compiler) and type checking (performed by the JVM runtime). This option was deprecated in JDK 8, and verification is now split by default without a ...

One important technique for achieving maximal performance in applications is the ability to split intensive tasks into chunks that can be performed in parallel to maximize the use of computational power. Dealing with concurrent (parallel) programming has traditionally been difficult, because you have to...
so on modern hardware you will get a lot higher performance out of a list implemented on top of an array. An array stores data sequentially. The CPU caches can load bigger chunks of the array into the cache at a time, and have the CPU access the data directly in the CPU cache once ...
Entities are now saved separately from terrain chunks 实体现在与地形区块分开保存 Expandedblockfield on block predicate toblocks block字段将被作为方块谓词扩充为blocks字段 Expandeditemfield on item predicate toitems item字段将被作为物品谓词扩充为items字段 ...
Block storage format in chunks slightly changed to speed up various tasks (rendering, pathfinding, world generation, etc). 区块中的方块存储格式有了些微变化,以加速各类任务(渲染,寻路,世界生成等)。 Added alocatebiomecommand 添加了locatebiome命令 ...
