I noticed when I put the itemSize of the cdk virutal scroll to a lower amount the loading time of the page is almost double the amount.
There is a hugh differents between <cdk-virtual-scroll-viewport [itemSize]="45"
and <cdk-virtual-scroll-viewport [itemSize]="20"
(a table with 2k rows).
My question is why loading of the page goes from 2 seconds to almost 5 seconds? How can it be such a big differents?
