Have you tried using Cloudflare? It might solve your problem.

This is not really something that makes sense as a plugin, probably best to solve it at the server level.

This problem no resolve cloudflare or dedicted server, because this request can will be on this dedicated server or cloudflare, i want a php-code in a plugin who can stop 100/sec request by the same ip address ..its easy to create this , today i create a php file with this but i need more .. .

To create a plugin for this should be indeed easy, at least at first glance.

1. getip(),
2. save in DB, and count++,
3. if count>100 then prevent from access.

However, the q2a engine would still handle it. So I guess best would really be something server-based.

Here is a shell script: http://linuxgazette.net/137/takefuji.html
