Hi!

Filling the forum now, everything is working fine) But as it fills one problem will arise.  
I have about 30 categories, and about 1500 subcategories. I notice that the more subcategories, the longer the main page takes to form (about 5 seconds at the moment). Other than that, it works pretty fast. My configuration is 4 cores, 6 GB RAM, SSD. The shared buffers are set to 1.5 GB.  
Maybe there is some ready-made recommendations how to increase loading speed of the main page? I don’t think the problem is in the postgresql sampling, I think it is in the rendering of the main page.  
Thank you.
