            <title>[SERVER-23333] Regression test for allocator fragmentation</title>
                <link>https://jira.mongodb.org/browse/SERVER-23333</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;We need a new regression test related to allocator fragmentation. The test should monitor the peak fragmentation experienced by TCMalloc on a particular workload known to cause significant fragmentation.&lt;/p&gt;

&lt;p&gt;Pass/fail criteria depends on measurements before/after our TCMalloc tuning changes.&lt;/p&gt;</description>
