   <h2>fastjson 2.0.54版本发布,性能进一步提升</h2>
   <p>这又是一个性能优化Bug修复的版本更新版本,大家按需升级。</p>
   <h1>1. 性能优化</h1>
   <p>这个版本的性能优化包括:</p>
   <h2>1.1 使用SWAR(SIMD Within A Register)技巧来优化序列化字符串的性能</h2>
   <p>序列化时,写字符串检测是否存在特别字符是一个性能关键点,这个版本使用SWAR(SIMD Within A 
Register)的技巧来做快速检测。如下</p>
   <pre lang="java"><code>package com.alibaba.fastjson2;
   class JSONWriterUTF8 {
       protected final long byteVectorQuote;
   <p>JSONWriterUTF8(Context ctx) {<br />
   // &quot; -&gt; 0x22, ' -&gt; 0x27<br />
   this.byteVectorQuote = this.useSingleQuote ? 0x2727_2727_2727_2727L : 
0x2222_2222_2222_2222L;<br />
   }</p>
   <pre><code>public void writeStringLatin1(byte[] value) {
       final long vecQuote = this.byteVectorQuote;
       int i = 0;
       final int upperBound = (value.length - i) &amp;amp; ~7;
       // 这里一次检测8个byte是否存在特别字符
       for (; i &amp;lt; upperBound; i += 8) {
           if (containsEscaped(IOUtils.getLongLittleEndian(value, i), 
vecQuote)) {
               break;
           }
       }
       // ...
   }
   
   static boolean containsEscaped(long v, long quote) {
       /*
         for (int i = 0; i &amp;lt; 8; ++i) {
           byte c = (byte) data;
           if (c == quote || c == '\\' || c &amp;lt; ' ') {
               return true;
           }
           data &amp;gt;&amp;gt;&amp;gt;= 8;
         }
         return false;
        */
       long x22 = v ^ quote; // &amp;quot; -&amp;gt; 0x22, ' -&amp;gt; 0x27
       long x5c = v ^ 0x5c5c5c5c5c5c5c5cL;
   
       x22 = (x22 - 0x0101010101010101L) &amp;amp; ~x22;
       x5c = (x5c - 0x0101010101010101L) &amp;amp; ~x5c;
   
       return ((x22 | x5c | (0x7F7F_7F7F_7F7F_7F7FL - v + 
0x1010_1010_1010_1010L) | v) &amp;amp; 0x8080808080808080L) != 0;
   }
