            <title>[SERVER-22831] Low query rate with heavy cache pressure and an idle collection</title>
                <link>https://jira.mongodb.org/browse/SERVER-22831</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;ul&gt;
	&lt;li&gt;single-node replicat set, 3 GB cache, 20 GB oplog&lt;/li&gt;
	&lt;li&gt;insert 10 M x 1 kB documents (10 GB total size, plus index)&lt;/li&gt;
	&lt;li&gt;then 100 threads querying documents at random, observe low query rate&lt;/li&gt;
	&lt;li&gt;then restart mongod, same queries are now much faster&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;&lt;span class=&quot;image-wrap&quot; style=&quot;&quot;&gt;&lt;img src=&quot;https://jira.mongodb.org/secure/attachment/110428/110428_queryrate.png&quot; width=&quot;100%&quot; style=&quot;border: 0px solid black&quot; /&gt;&lt;/span&gt;&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;A-B: collection is being created&lt;/li&gt;
	&lt;li&gt;B-C: random queries
	&lt;ul&gt;
		&lt;li&gt;query rate is very low, ~6 k/s&lt;/li&gt;
		&lt;li&gt;rate of evicting from and reading into cache is ~9 k pages/s, ~1.5 pages per query, so very high miss ratio&lt;/li&gt;
		&lt;li&gt;rate of pages walked for eviction is very high, ~21 M/s, so about 2300 pages walked for every page evicted, or 2-3% of pages in cache walked for every page evicted&lt;/li&gt;
		&lt;li&gt;no pages are being evicted from oplog, but it is uncertain whether that is because all pages have already been evicted&lt;/li&gt;
	&lt;/ul&gt;
	&lt;/li&gt;
	&lt;li&gt;C-D: after restart
	&lt;ul&gt;
		&lt;li&gt;query rate is much higher, ~34 k/s&lt;/li&gt;
		&lt;li&gt;rate of evicting from and reading into cache is 26 k pages/s, ~0.75 pages per query, so lower miss ratio than before restart&lt;/li&gt;
		&lt;li&gt;rate of pages walked for eviction is much lower&lt;/li&gt;
	&lt;/ul&gt;
	&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;The issue does not reproduce on a standalone node.&lt;/p&gt;

                            <comment id="1187146" author="alexander.gorrod" created="Mon, 29 Feb 2016 04:00:57 +0000"  >&lt;p&gt;Thanks &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=bruce.lucas&quot; class=&quot;user-hover&quot; rel=&quot;bruce.lucas&quot;&gt;bruce.lucas&lt;/a&gt; Your analysis matches what we saw in our testing, and the fix made above to WiredTiger should resolve this new scenario as well. The reason the performance differs is that WiredTiger was evicting all leaf pages from the idle connection, but it adds a selection of pages from each tree it visits to a list of eviction candidates. It would add some internal pages from the idle tree and some leaf pages from the non-idle tree. It would always choose to evict the leaf pages since we deprioritize eviction of internal pages. So we walk the internal pages without benefit, and populate half the eviction queue with pages that are very unlikely to be evicted.&lt;/p&gt;

&lt;p&gt;The fix we made was to limit the number of internal pages added to the eviction queue.&lt;/p&gt;</comment>
                            <comment id="1185966" author="bruce.lucas@10gen.com" created="Fri, 26 Feb 2016 16:21:46 +0000"  >&lt;p&gt;Note that this doesn&apos;t require an oplog, nor a transition to read-only. All that&apos;s necessary I believe is&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;heavy cache pressure&lt;/li&gt;
	&lt;li&gt;more than one collection&lt;/li&gt;
	&lt;li&gt;one collection is in cache and then becomes idle&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;For example:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;two identical collections, 10 GB each (10 M documents x 10 kB)&lt;/li&gt;
	&lt;li&gt;standalone (no oplog), 3 GB cache&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;&lt;span class=&quot;image-wrap&quot; style=&quot;&quot;&gt;&lt;img src=&quot;https://jira.mongodb.org/secure/attachment/110885/110885_two-collections.png&quot; width=&quot;100%&quot; style=&quot;border: 0px solid black&quot; /&gt;&lt;/span&gt;&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;E-F: reading randomly from collection 1&lt;/li&gt;
	&lt;li&gt;G-H: reading randomly from collection 2&lt;/li&gt;
	&lt;li&gt;I-J: reading randomly from collection 1 again&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;In each case the rate of reads immediately after transitioning to a new collection is high, but once all the leaf pages of the collection that has become idle have been evicted to make room for the newly active collection, the performance issue is triggered: rate of pages walked for eviction becomes high, rate of queries drops.&lt;/p&gt;</comment>

However there is also a signficant performance regression on this test in 3.2.3 vs 3.0.9 that appears in a standalone test (whereas the issue on this ticket only appears with a replica set); opened &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-22834&quot; title=&quot;1.7x performance regression in random queries&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-22834&quot;&gt;&lt;del&gt;SERVER-22834&lt;/del&gt;&lt;/a&gt; to track separately, although it is possibly related as it also appears to involve a high rate of pages walked per page evicted.&lt;/p&gt;</comment>
