LuaJIT has been successfully used as a <b>scripting middleware</b> in
186
 
games, appliances, network and graphics apps, numerical simulations,
187
 
trading platforms and many other specialty applications. It scales from
188
 
embedded devices, smartphones, desktops up to server farms. It combines
189
 
high flexibility with <a href="http://luajit.org/performance.html"><span class="ext">&raquo;</span>&nbsp;high performance</a>
190
 
and an unmatched <b>low memory footprint</b>.
191
 
</p>
192
 
<p>
193
 
LuaJIT has been in continuous development since 2005. It's widely
194
 
considered to be <b>one of the fastest dynamic language
195
 
implementations</b>. It has outperformed other dynamic languages on many
196
 
cross-language benchmarks since its first release &mdash; often by a
197
 
substantial margin.
198
 
</p>
199
 
<p>
200
 
For <b>LuaJIT 2.0</b>, the whole VM has been rewritten from the ground up
201
 
and relentlessly optimized for performance. It combines a <b>high-speed
202
 
interpreter</b>, written in assembler, with a <b>state-of-the-art JIT
203
 
compiler</b>.
204
 
</p>
205
 
<p>
206
 
An innovative <b>trace compiler</b> is integrated with advanced,
207
 
SSA-based optimizations and highly tuned code generation backends.
208
 
A substantial reduction of the overhead associated with dynamic languages
209
 
allows it to break into the performance range traditionally reserved for
210
 
offline, static language compilers.
