Speeding up rails queries - ruby-on-rails

Question

I've got a table that contains 10k products. When I query the database after a server restart, the server is querying all of the 10k products and then limits to 15 records in the response. Is this normal? It is causing my page to take 23 seconds for the first page to load. Upon the second request, everything looks better, but I still don't understand why the first query is grabbing all of those records.
My Query:
#products = Product.limit(15)
The first response:

#SteveTurczyn pointed out my issue which ended up being rather simple. The problem involved calling an import function for Elastic Search which was in my Product model. After I removed the line of code, everything worked as expected. Here is the code that slowed down the process.
Product.includes(normal_model: [:normal_brand]).import force: true
I now have a controller method that invokes the import function when needed.
