            <title>[SERVER-2297] when adding a replica, especially a delayed replica allow for throttling of initial replication to avoid spikes</title>
                <link>https://jira.mongodb.org/browse/SERVER-2297</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;When adding a delayed standby we saw response times go from ~2ms to ~20ms during the period the data was being replicated.   We plan on having the dataset grow to a much larger level and thus the spike duration would be longer.  We would like a feature that allows throttling of initial replication so the spike is smaller but perhaps longer.  This must be weighed against never being able to catch up if it&apos;s throttled too far.&lt;/p&gt;</description>

I think that solves the issue in a cleaner way.&lt;br/&gt;
Resolving for now, let me know if you think it doesn&apos;t&lt;/p&gt;</comment>
