Our website has a slow loading time (tools.pingdom.com => 2s waiting). This is apparently the time to first byte. How can you make the website faster? We only activated the visual composer plugin. Images are made smaller. Any cache plugin gives only white pages. Also tried to put the website on other server but same results. I am out of ideas. Do you still have?
You can try to delete all pages/ post that you do not use. Also a cache plugin is the most recommended. You can find in link1 and link2, some advice on how to speed up your site.
