Chrome browser is slow on first load

Hi,

I have a load time of about ten seconds which only occurs on Chrome browser and on the first load.
Then it starts over every 5 minutes or so...
I specify that the certificates are valid, that no chrome extension is activated and that I am on Docker for Mac.
