Question appropriate flood protection time?

what is a good number to set for flood protection without degrading performance?

thank you

Thanks for an interesting question. It's a bit difficult to advise what's "appropriate" to your circumstances. It's a question like "how much string do I need to tie up a parcel"; it depends on the size of the parcel. In the same way, it depends on how sizeable is the issue you're having with forum flooding. This forum (at www.kunena.org ) is quite busy but I cannot remember seeing a case where the behaviour of one or two people who tried to flood the forum with rubbish posts lasted more than a short while.

We have our own way of dealing with flooding posts. If someone posts, say, several messages that do not contribute to the value of this forum over a very short space of time (in other words, tries to flood the forum) we just ban and delete the messages. That's how we deal with topic flooders. Therefore, in this forum, we do not use "flood protection time" because there's no need for it.

I would suggest the same in your case unless "flooding" is a persistent and ongoing daily occurrence. I am not aware of any degradation to system performance if you implement the flood protection mechanisms built into Kunena. If you want a "good" number, try one minute and see how it works for you. If that's no good, try something else.

Flood protection just prevents user from posting more messages during x seconds. There's no performance gain, just helps against bots or too eager users (giving one word replies).
