I have built a website for a community in the last year. In the last few days I realised that it has become a very slow one.
I found out that two plugins (Polylang and All In Event Calendar) causes a lot waiting time. If I deactivate them then the website is fine. These two plugins put a lot stress on the server.
I use the GTmetrix website to check for optimization the sites. According to this site the webpage is well optimised (could be better anyway).
My question is if I would upgrade the host it would make much difference? Now I use the Business package at 123reg and I would go with the premium S. Both shared host. There is no money for VPS.
