Hi all,
I have two websites (http://www.grondbezit.nl and http://www.gastvrijelandgoederen.nl) running on Contao hosted at XS4ALL (http://www.xs4all.nl) in Amsterdam. XS4ALL is the first and still leading, most secure, one of the biggest and most expensive :-( provider in The Netherlands. So they're no amateurs, just to make that clear.
On the whole Contao works rather slow at XS4ALL. Page loads in backend and frontend of about 3 to 5 seconds are normal. At some moments the system almost comes to a halt (30 to 120 secs). After endless calls with customer support, I got a link to a page maintained by one of the system managers at XS4ALL . I also had personal contact with him. He tells me, the problem lies in the internal architecture of Contao (the number of requests Contao sends to the database). Because of the extreme 'high availability settings' at XS4ALL, these speed problems of Contao are not 'masked' like with other providers. That is what he told me. Hmmm, obviously high availability for some, means low availability for others.
This is the page by system manager Daniël: https://daniel.mostertman.org/codex/Cms. Sorry, it's in Dutch only, but I guess you will understand it. He made an overview of the most commonly used CMSs and how they run on XS4ALL's servers. In the summary table at the beginning of the document it is stated that Contao is "Extremely inefficient / slow, but very beautiful and user friendly". At the end of the document you can find more details on the problem.
What is your opinion on this? Do you think this is a solvable problem? If not, I'll have to change providers, which is a hassle of course...
Thanks in advance,
Just
