Chrome automation - Puppeteer - Js heavy webpage

Created an automation in headless puppeteer, configured this in a Render starter instance.
However, it is taking too much time on loads around 60/70s to complete the whole flow however, around 40secs of this 60 is just the load of the first page, not sure why this start takes so much time. (Headless locally takes about 10secs).

Can someone advice if scaling the service to a Standard instance will make this first step faster?
Feel free to ask for more information if needed.
