I've seen several drupal sites where you have to answer a maths question to post a comment (What is 7+3?). Which module offers this functionality?

How much does captcha effect the performance of the server i.e. does it slow down the page load process and if so is it a lot or hardly noticeable
Also what about the spam module? is that any good

which is better spam module or captcha? (I read somewhere that captcha is not very disable friendly)

Servus.

Site load performance is a tricky thing, but in general you can consider the time for generating pages with PHP the fastest part of the game. Accessing the database is a lot more "expensive", let alone transferring the site over the web. I have no idea how reliable the Drupal stats thing is, but I was almost shocked that after one week of working on some client's site I got only some 8 minutes of CPU time logged on the server... Sheesh, better don't let the client know :)

When it comes to transfer times there are many things to rule out before having to care about captcha... After all, I'd say you can concentrate on other things and install captcha as a nicely working "black box" (at least with the Math question basic option) -- my clients love it.

I never dealt with spam module, but I had no problem with captcha (I might misunderstand the term "disable friendly", however). I set the roles and modules where captcha should kick in and it does just what I told it...

I never had any luck using the images in the Captcha module due to user browser cache issues. In other words, it would keep legitimate users from posting comments too because they would have an old cached image in their own browser cache that their browser would display instead of the new one that matched what the Captcha module was expecting. Very frustrating.

Since I've changed it to the Maths questions however, Captcha has performed beautifully and has cut down on my spam immensely.

Servus.

Although I think Captcha does a pretty good job, the two staged "Preview" and "Post" process (as used here) should also help a lot to keep bots from spamming...
