String Concatenate 比 StringBuilder (StringBuffer) 慢？带着这样的疑问，决定好好的亲自试验一番。
XML parsing cost is linear in the size of the filter expression, but incurs a much higher unit cost than actual expression evaluation. Though lightweight, expression evaluation exhibits non-linear slowdown as the size of the expression grows. ...
