I just ran my usual benchmark and it seems a performance regression has been fixed and some performance added over that. I&amp;#x27;m measuring the speed of loading a Sony A77 raw file in rawloader[1]. That includes TIFF parsing and then a tight loop that processes every pixel. Here&amp;#x27;s the version history:&lt;p&gt;1.17 - 95ms&lt;p&gt;1.18 - 80ms (-16%)&lt;p&gt;1.19 - 79ms (-16%)&lt;p&gt;1.20 - 80ms (-16%)&lt;p&gt;1.21 - 79ms (-17%)&lt;p&gt;1.22 - 79ms (-17%)&lt;p&gt;1.23 - 79ms (-17%)&lt;p&gt;1.24 - 84ms (-12%)&lt;p&gt;1.25 - 74ms (-22%)&lt;p&gt;I believe the jump in 1.18 was LLVM 4.0 and now LLVM 6.0 is giving me a new performance jump. No idea what happened in 1.24 though but it seems to be fixed now.&lt;p&gt;[1] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;pedrocr&amp;#x2F;rawloader&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;pedrocr&amp;#x2F;rawloader&amp;#x2F;&lt;/a&gt;</text><parent_chain><item><author>kibwen</author><text>The big thing in this one is the LLVM upgrade, which has been a &lt;i&gt;long&lt;/i&gt; time coming. :) We actually skipped LLVM 5 entirely due to some issues with emscripten.
