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