To what extent does the site loading speed depend on the content management system (cms)?

Question

CMS

Is there any comparative statistics on the dependence of the speed of the return of the pages of the site on its engine with the same other parameters? Any experiments in this area, research?
If the dependency is obvious, then which cms is the fastest (for a php environment)? What is considered "fast" for online stores?
And finally, where in the Wordpress speed rankings?
ps
I especially thank you if the answer will be based on the evidence base, refer to specific facts and links.

Answer 1

Everything is detailed here and here .

Answer 2

The question is ambiguous.
Synthetic tests for Hello Word are not very revealing.
Under load, caching decides everything.
The most hellish assembly I've seen is caching the final HTML with a memcache, and returning caches through Nginx straight from the RAM, without touching the file system at all.

Answer 3

In the speed rating, WP is about in the middle - it is faster than other popular CMS (Drupal, joomla, if we take the standard configurations of the LAMP stack in booth and take all CMS without plugins), but slower than more specific CMS, which have fewer functions.
In general, the work of any cms strongly depends on the number and quality of plugins + the quality of the made-up template. My WP gives a face for 550-700 ms, of which 300 - in fact, page generation - looks like a static site in terms of speed after the second opening (ssl-handshake on the first connection spoils all the raspberries + competent caching on the client).
As for the fast ones for stores - shopcms was fast, it compiled smarty blocks out of the box into pure html the first time they were accessed. But the encrypted (cheap) version requires php5.2, which you won’t find in the daytime with fire, and there is no longer any support there.
