So I have a mission in making pages faster and faster and here is my thoughts and I would really like some feedback and comments to discuss if this is a really bad way or if it is a really smart way 
I have a Data Collection with 1,000 records and I added those records to a table on my page using the $table.rows. Then I just made the code different so that it would split all data up in pages with 25 records on every page. I added a pager so the user can browse through all 40 pages with dummy data.
But I thought that the page loads a bit slow so I started to think about some way of making my own Data Collection Cache on top of the already great cache mechanism. What did I do?
I take the first 25 records as the JSON object needed for the table and I just store the whole chunk of that in a Data Collection I call Cache. Then when a user hits my page I just load the last available record from that Data Collection and populate the table.
Now I think I saw some great increase in performance because the data reads one record and it is already formatted for the table so it performs really fast I think.
First version where I populate from data through backend code but still read records from the Data Collection was between 6.6 seconds up to 9.4 seconds on GTMetrix for a fully loaded page. This is really fast I think, then I went to Pingdom to test the load time without regards to the fully loaded and went from 2 seconds down to 309 ms and that is like my personal record in Wix.
So the version where I cache JSON in a separate Data Collection is fully loaded at 4.4 seconds and that is around 60% faster than the already fast one.
Getting a page speed score of 98% at GTMetrix is kind of hard in my experience.
So what I will do now is to create a Data Hook that will will refresh the cached data in the background on a schedule so I know that the users get the freshest data but maybe cached for 4 hours or even 24 hours depending on the usage.
So what is your feedback on this?

Try it and see what you think, is this a faster way to store all records in one cached field for the start page of my site or is it just me playing around like an amateur as usual?
Well, anyway, happy coding in the greatest platform of all times!
Also, how did you do that? It is really fast.
