Now that this version has been out a while, are you more open to having this updated for the 5.0 release?  &lt;/p&gt;</comment>

                            <comment id="3269297" author="oliver@sensortower.com" created="Thu, 2 Jul 2020 21:43:06 +0000"  >&lt;p&gt;I want to add that according to the website&#160;&lt;a href=&quot;https://github.com/facebook/zstd&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/facebook/zstd&lt;/a&gt;.&#160;&#160;&lt;/p&gt;

&lt;p&gt;zstd is now (at --fast 7)&#160; 38% faster than snappy in both compression and decompression speed at the same compression level.&#160; This would make zstd a no-brainer replacement for snappy.&lt;/p&gt;</comment>
                            <comment id="3262029" author="oliver@sensortower.com" created="Wed, 1 Jul 2020 15:34:50 +0000"  >&lt;p&gt;Agreed!&#160; 5-10% improvement in decompression speed is huge.&#160;&#160;&lt;/p&gt;
