limiting apache requests

[Marek Podmaka <marki@onee.sk>]

Hello,

  Do you have any experience with limiting number of apache (1.3)
  requests per IP or per vhost?

  I have found these packages, but I couldn't find more information
  about how stable and useful they are:

  libapache-mod-tsunami
  libapache-mod-choke

  And do you use mod-security? How much mem & cpu does it take? Is it
  worth?

      thanks
