            <title>[STCON-85] Inventory, Users etc Slow and Glitchy on View and Edit</title>
                <link>https://folio-org.atlassian.net/browse/STCON-85</link>
                <project id="10189" key="STCON">stripes-connect</project>
                    <description>&lt;p&gt;Steps to repro:&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;Log into folio-testing&lt;/li&gt;
	&lt;li&gt;Go to Inventory&lt;/li&gt;
	&lt;li&gt;Edit an Instance record&lt;/li&gt;
	&lt;li&gt;Add a repeatable element such as an identifier&lt;/li&gt;
	&lt;li&gt;Type into the identifier field - it takes a long time for the test you entered to display&lt;/li&gt;
	&lt;li&gt;Please watch screencast - there are tons of issues here - too many to write up&lt;/li&gt;
	&lt;li&gt;Another issue: go to Inventory, find an item record and view it, search for another instance and then open an item within that instance.  It takes several seconds for the item data to refresh and show the relevant data for the selected item (it is showing the data from the previously viewed item for several seconds)&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;Expected: Entered text displays right away&lt;/p&gt;

&lt;p&gt;Actual: Field is empty for 10+ seconds before the entered text displays&lt;/p&gt;

&lt;p&gt;Additional info: the above is just one example of generaly slowness and glitchyness in Inventory lately.  Ann-Marie passed on this feedback:&lt;br/&gt;
&quot;When I type things into search boxes, it takes a few seconds for the typing to catch up - in users, checkin/checkout, inventory, etc....  Also, I kept pasting the search twice, and then having to back it out, and having to wait for the backspace to kick in. Ugh&quot;&lt;/p&gt;

            &lt;/span&gt;
&lt;/li&gt;
	&lt;li&gt;Settings &amp;gt; Circulation &amp;gt; Circ rules: Deleting patron notice policy takes too long &lt;a href=&quot;https://www.screencast.com/t/5dsZUteT&quot; class=&quot;external-link&quot; rel=&quot;nofollow noreferrer&quot;&gt;https://www.screencast.com/t/5dsZUteT&lt;/a&gt;&lt;/li&gt;
	&lt;li&gt;Requests: Sometimes clicking the request queue number withing the request takes too long to show you the request queue list in the search results&lt;/li&gt;
&lt;/ul&gt;

The borders that show up indicate which components are being re-rendered. You can see it&apos;s basically the entire form every time. &lt;/p&gt;

&lt;p&gt;I don&apos;t know if this is an issue with redux-form itself or merely the way we are using redux-form, but it&apos;s clearly not helping us any.&lt;br/&gt;

That&apos;s gives us a lot of potential options to investigate, but it ... gives us a lot of potential options to investigate. &lt;/p&gt;

&lt;p&gt;I&apos;m working backwards with the &lt;tt&gt;snapshot&lt;/tt&gt; branch&apos;s &lt;tt&gt;yarn.lock&lt;/tt&gt; file (it&apos;s updated automatically every hour) to see if I can find a performance tipping point, (think &lt;tt&gt;git bisect&lt;/tt&gt;) but it&apos;s a slow process. &lt;/p&gt;</comment>

Essentially we were not correctly filtering a stream of events for changes and therefore our components did not always update as expected. Unfortunately, correctly filtering that stream is costly in terms of performance.&lt;/p&gt;

&lt;p&gt;We are trying to figure out if we can have our cake and eat it too.&lt;/p&gt;</comment>

I reverted locally the change and they started to work.&lt;/p&gt;

&lt;p&gt;As I found it happens because the &lt;b&gt;arePropsEqual&lt;/b&gt; function may happen to deal with react elements which are pretty deep objects. As I tried locally omitting such may resolve the issue.&lt;/p&gt;

Users feels like it is working much better but I am still seeing the issue in Inventory where you type in a field and the entered text takes a long time to display.  Reopening.&lt;/p&gt;

I feel like we did everything possible given our current architecture (stripes-connect, redux-form). In order to improve it we would have to restructure things significantly (replace redux-form and switch to GraphQL).&lt;/p&gt;

&lt;p&gt;But I would suggest reviewing this in folio-snapshot. The fix is already there and it should perform a bit better. The reason for it is that the snapshot env is built in production mode which improves the react performance. I&apos;m hoping it will be good enough for the time being.&lt;/p&gt;

I see these errors in folio-testing:&lt;/p&gt;

&lt;p&gt;&lt;em&gt;You are currently using minified code outside of NODE_ENV === &apos;production&apos;. This means that you are running a slower development build of Redux. You can use loose-envify (&lt;a href=&quot;https://github.com/zertosh/loose-envify&quot; class=&quot;external-link&quot; rel=&quot;nofollow noreferrer&quot;&gt;https://github.com/zertosh/loose-envify&lt;/a&gt;) for browserify or DefinePlugin for webpack (&lt;a href=&quot;http://stackoverflow.com/questions/30030031&quot; class=&quot;external-link&quot; rel=&quot;nofollow noreferrer&quot;&gt;http://stackoverflow.com/questions/30030031&lt;/a&gt;) to ensure you have the correct code for your production build.&lt;/em&gt;&lt;/p&gt;

&lt;p&gt;This was already fixed so I&apos;m not sure why we see it again. I think after this is fixed again folio-testing should also perform a bit better too.&lt;/p&gt;</comment>

I do think we will need to restructure things, as the performance is still too slow.  But I understand that that&apos;s a bigger issue and out of scope for this release.&lt;/p&gt;

&lt;p&gt;Things have improved significantly from when I first filed this ticket.  I don&apos;t think the performance is a release blocker at this point so I will close this as done.&lt;/p&gt;

&lt;p&gt;Thanks for all your help with this.  We&apos;ll come back to the architecture restructure question later.  &lt;/p&gt;</comment>

Thank you &lt;a href=&quot;https://folio-org.atlassian.net/secure/ViewProfile.jspa?accountId=5af5ed55244bc90a106063c7&quot; class=&quot;user-hover&quot; rel=&quot;5af5ed55244bc90a106063c7&quot; data-account-id=&quot;5af5ed55244bc90a106063c7&quot; accountid=&quot;5af5ed55244bc90a106063c7&quot; rel=&quot;noreferrer&quot;&gt;Cate Boerema&lt;/a&gt;! Yes there are couple steps we can take to improve the overall performance. The big one will be to move away from redux-form. &lt;/p&gt;</comment>
