​Its configured

But the F5 is so fast, that it does not triger it. I actually can rate limit http requests using Nginx instead. But a single page can make many requests, and in the end, the page gets slower.

​I rate limited to 4 r/s for PHP, i would love to have 2, but under 4 will be blocked (when using ajax search, it sends bunch of requests like a ddos in ACP)

Also got 6 cores * 3.7 GHz, goes down if its fairly large but not one person lol oh and upgraded to 2gb ram but still half isnt used lol

Also, with IPS4 you can enabled the Page Cache for Guests. That will work for any guest or bot that hammer you with http requests.

To the ones that are having this problem and using apache, the module mod_limitipconn limits the connections per IP and pressing F5 for some seconds will result in a 503 error page. This is one possible solution and a very good one.

Does anyone have a solution to this thing?

How can we prevent flooding by F5? It also drops my server. How can we prevent or stop the flood by clicking f5?

thanks,

​If you are using Apache, install mod_limitipconn and set the maximum number of connections per IP.

I am sorry, but that´s just due to poor setup of your MySQL/Whatever SQL Server you use and due to bad nginx/apache configs.

 

It is a shame how many people use the standard configs.

 

IPB is and will always be ressourcehungry, due to the fact that most stuff needs to be fetched from the db. You may need to consider setting up your server good enough to make sure that you save some of those ressources.

If using nginx, it should be a simple matter of 

  limit_conn limit_per_ip 32;

in the vhost definition.  Adjust the number to suit you.

You should limit both connections and requests on Nginx for better results
