[Discussion] Browser Unresponsive when Loading Entity with Large Results

Devanshu Vyas-2
Hello Guys,

Recently, I came across a situation where an entity was taking too much of
a time(browser asked me to either wait or kill) while loading/searching
results in the Webtools application. The entity had close to 5M records,
and I checked the server responded timely but the rendering of the screen
was taking time.
When I explored the issue I came across a macro which renders the
pagination on the screen, and it had a code block which was causing the
screen rendering delay.
{code}

<#assign x=(listSize/viewSize)?ceiling>
  <#list 1..x as i>
    <#if i == (viewIndex+1)><option selected="selected"
value="<#else><option value="</#if>${i-1}">${i}</option>
  </#list>

{code}
This code seems logical enough to me, and what I gather from this is that
the list will render a select box with 250,000 options.

I would like to propose a change in this UI/UX from select box to an input
text box so a user can navigate to any page, similar to a navigation input
box in a PDF document reader application.

Please let me know your thoughts on this and share some more ideas to how
we can improve/resolve this issue. Looking forward to your replies!



Thanks & Regards,
Devanshu Vyas.

before proposing the solution we need a diagnosis. What is the strain
happening on the browser?

Re: [Discussion] Browser Unresponsive when Loading Entity with Large Results

Devanshu Vyas-2
Hello Taher,

The FTL is trying to render a list(select box) with a large number of
options(around 250,000 in my case) which takes a lot of time and the
browser usually asks to either kill the page or wait for it to load
completely.

Thanks & Regards,
Devanshu Vyas.

Re: [Discussion] Browser Unresponsive when Loading Entity with Large Results

Devanshu Vyas-2
Hello Taher,

The browser becomes unresponsive to a user in this case, as the browser is
busy in preparing the large '*select*' DOM element(a drop-down with around
250,000 options).
I found some points related to our discussion here
<https://developers.google.com/web/tools/lighthouse/audits/dom-size>.


Thanks & Regards,
Devanshu Vyas.

Re: [Discussion] Browser Unresponsive when Loading Entity with Large Results

taher
Yeah so what you are describing is a pagination issue right? The root
cause is pagination, not type of widget being used? I'm a little
confused by the proposal?

Re: [Discussion] Browser Unresponsive when Loading Entity with Large Results

Deepak Dixit-4
Pagination widget tries to generate select with a huge number of options so
browser takes too much time to prepare dom and causing unresponsiveness.

So we can say that the root cause is in the pagination widget that
prepares select option. We need a different pattern rather than select
element for rendering the page (VIEW_INDEX)

Thanks & Regards

Ahh, so you want an auto complete text box that fetches from server on
the fly using jQuery right? If so, sure +1

Re: [Discussion] Browser Unresponsive when Loading Entity with Large Results

Deepak Dixit-4
Yes, something like this or even we can have a simple text box to enter the
page value or a much better solution.

Devanshu, Could you please open a ticket for this improvement?
