+### 性能测试
+简单做了一下性能测试，用例如下：
+- 1000个过滤词
+- 100,000个字符的文本源
+- 完成不同次数的过滤
+
+测试环境：我的2016款MacbookPro
+
+测试结果：
+```bash
+# 第1次测试
+Loops:10, time cost(ms):194, avg(ms):19.4
+Loops:100, time cost(ms):405, avg(ms):4.05
+Loops:1000, time cost(ms):3088, avg(ms):3.088
+# 第2次测试

+Loops:100, time cost(ms):419, avg(ms):4.19
+Loops:1000, time cost(ms):3172, avg(ms):3.172
