How secure is Joomla 3.3?

Question

CMS

We are going to implement a project on Joomla 3.3. Heard a lot of "+" and "-", interesting, in your opinion, how safe and stable is Joomla 3.3? With visits of more than 10,000 people a day, will it lag and slow down?

Answer 1

I confirm that I have 17 Joomla sites on VDS with a total daily traffic of 7-8 thousand, several sites with the JoomShopping e-commerce component. CPU load 7-8%, database server load 9-11% (on the same VDS).
PS do not forget to put root rights on the folder with Joomla, in order to avoid accidental infection.

Answer 2

Of course it's not safe.
Update urgently - I wrote more on the blog and made patches

Answer 3

if you take the stable latest version of joomla and do not shove extensions into it, everything is fine. Otherwise it all depends on what and how you use it.
