“StringBuffer”可以造什么句，StringBuffer造句

However, there is a performance penalty here, since a StringBuffer must work to transparently increase its size and shift the data around.

对String和StringBuffer来说，完成测评所需要的时间随着计划长度的增加呈指数级增长。

为创建串联的字符串 “ssRights” ，编译器将创建一个临时的StringBuffer对象，调用StringBuffernd 三次，然后调用StringBufferring ，这意味着至少两个对象的创建和几个方法调用。

Given the single threaded nature of this benchmark, I was fully expecting Escape Analysis to elide the lock thus rendering StringBuffer performance equivalent to that of StringBuilder.

举例来说，考虑一下线程安全的StringBuffer的用法。

明确了这个基准测试的单线程化的本质后，我期待着逸出分析会消除锁，从而将StringBuffer的*能提到了与StringBuilder相同的水平。
