Performance Impact of Markup Regions

[thausmann 5]

Hey, I just refactored my site to use markup regions and noticed slower responses / rendering times by two-four times.

I'm having a landingpage with a Pagetable that has 15 blocks, most of them have a little CSS with mediaqueries that I can now put in the header with pw-append, which is nice, but seems especially costly to do it 15 times. I put together a minimal example showing the speed impact: https://gist.github.com/timohausmann/e7643d75e26135450dab63e33c94de8f

This effect scales up so my real page went from 600ms to 3.2s. The page gets cached in the end so it's not a total deal breaker, but I'm wondering if I'm doing something wrong, or if this is normal and markup regions and pw-append aren't designed to be used repeatedly?

Thanks for reading!

for those who experience the same problem on windows, especially large html content.

<div id="content">...</div> // 10x slower for me

<region id="content">...</region> // fast no problem

I always use:

<pw-region id="content">...<pw-region>  

..works like a charm
