I'm trying to improve the Server Response Time of an angular 6 app. At the beginning this app was being hosted as simple production of angular over an apache2 web server. After I updated this app to universal, meaning now it is being run over node.js with express, I noticed that the Server Response time increased really high. I tried using cache headers but nothing seam to make a difference.
The comparison is illustrated by inspecting the network on google chrome:
BEFORE
AFTER
Could this be because of the proxy or redirection to the port which the app is listening ?
