> The current hardcoded values for the {{page_size}} on {{AirflowModelView}} is set to
{{500}} rows, which is usually too large to render in less than 1-2 secs in modern browsers.

> Also, in some endpoints it is also taking a long time to render server-side the HTML
content for 500 rows, taking around 1-2 secs (on the server) or sometimes more.
> Simple approach is to reduce this value to something more sensible (100 maybe?). Probably
making it a configurable value would be a good option too in case the default is not good
> See attachment for a profiled sample of a page loading time.
