| 192 PCRE JIT can speed up processing of regular expressions significantly. | |
| 193 <note> | |
| 194 The JIT is available in PCRE libraries starting from version 8.20 | |
| 195 built with the <literal>--enable-jit</literal> configuration parameter. | |
| 196 When building the PCRE library with nginx (<literal>--with-pcre=</literal>), | |
| 197 the JIT support should be enabled with the | |
| 198 <literal>--with-pcre-jit</literal> configuration parameter. | |
