Don't worry about the synchronous problems in this case, the function here is thread-safe (or should be called goroutine-safe).
+## Pre-malloc goroutine queue in pool
+
+`ants` allows you to pre-allocate memory of goroutine queue in pool, which may get a performance enhancement under some special certain circumstances such as the scenario that requires an pool with ultra-large capacity, meanwhile each task in goroutine lasts for a long time, in this case, pre-mallocing will reduce a lot of costs when re-slicing goroutine queue.
+
+```go
+// ants will pre-malloc the whole capacity of pool when you invoke this function
+p, _ := ants.NewPoolPreMalloc(AntsSize)
+```

+## 预先分配goroutine队列内存
+
+`ants`允许你预先把整个池的容量分配内存， 这个功能可以在某些特定的场景下提高协程池的性能。比如， 有一个场景需要一个超大容量的池，而且每个goroutine里面的任务都是耗时任务，这种情况下，预先分配goroutine队列内存将会减少re-slice时的复制内存损耗。
