My guess is that many ppl like me make Drupal websites just by using modules and simple CSS. Several content types, taxonomies, views, panels or DS to get results fast and more/less nice looking. Maybe add forum to all that.
When it comes to caching there are many options and i have no idea which ones to use. All my websites are on shared hosting (most popular ones).
In "performance" i always enable everything. Minimum cache lifetime and expiration of cached pages are options i always gaze at for several minutes and in the end choose "1 day". No idea if thats good. All other check boxes are clicked of course.
Views 3 are cached by default, nice, if i remember good i had to enable that in previous versions.
Now the fun part is picking modules from drupal.org for caching.
On this page Caching: Modules that make Drupal scale (updated 2014-07-09) we have 15 modules for D7. How many to use ? Which ones are "best" ? Which one you reccomend for shared hosting ? Should i for example disable default caching in performance and in views if i use those ?
So the final question would be: For nondevelopers who use shared hosting, what are the easiest/best modules - plugnplay.
