                            <customfieldvalue>&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/DRIVERS-2581&quot; title=&quot;Benchmark and use `mongocrypt_binary_t` definition to improve performance of In-Use Encryption&quot; class=&quot;issue-link&quot; data-issue-key=&quot;DRIVERS-2581&quot;&gt;DRIVERS-2581&lt;/a&gt;:&lt;br/&gt;
Goal: Improve performance of In-Use Encryption for the workload identified in HELP-27047.&lt;/p&gt;

&lt;p&gt;Proposed changes for drivers:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;Benchmark throughput of decrypting documents with many (e.g. 1500) encrypted fields. The benchmark is specified here: &lt;a href=&quot;https://github.com/mongodb/specifications/commit/db3114e957f7c0976a1af09882dbb46cb4a70049&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/specifications/commit/db3114e957f7c0976a1af09882dbb46cb4a70049&lt;/a&gt;&lt;/li&gt;
	&lt;li&gt;Attempt to use fields of `mongocrypt_binary_t` to avoid calls to `mongocrypt_binary_data` and `mongocrypt_binary_len`. The fields are exported as of &lt;a href=&quot;https://jira.mongodb.org/browse/MONGOCRYPT-589&quot; title=&quot;Export mongocrypt_binary_t&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MONGOCRYPT-589&quot;&gt;&lt;del&gt;MONGOCRYPT-589&lt;/del&gt;&lt;/a&gt;.&lt;/li&gt;
	&lt;li&gt;Expect an improvement in throughput.&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Refer to the changes made for the Java driver bindings:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;Benchmark added in: &lt;a href=&quot;https://github.com/mongodb/libmongocrypt/pull/690&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/libmongocrypt/pull/690&lt;/a&gt;&lt;/li&gt;
	&lt;li&gt;Use of `mongocrypt_binary_t` fields done in: &lt;a href=&quot;https://github.com/mongodb/libmongocrypt/pull/693&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/libmongocrypt/pull/693&lt;/a&gt;&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;The benchmark may be useful for testing future performance improvements (&lt;a href=&quot;https://jira.mongodb.org/browse/DRIVERS-2718&quot; title=&quot;Enable use of native crypto in libmongocrypt bindings&quot; class=&quot;issue-link&quot; data-issue-key=&quot;DRIVERS-2718&quot;&gt;DRIVERS-2718&lt;/a&gt;).&lt;/p&gt;

&lt;p&gt;Proposed changes may not apply to languages with no extra cost for calling into a C library: (C, C++, PHP via C driver)&lt;/p&gt;</customfieldvalue>
