MaxClients 150


If I set this figure higher that means more users can connect concurrently? Right?

Provided that you have sufficient cpu power and memory to handle them, yes.

As a sidenote, Apache usually limits the maxclients to 256 no matter what you set the maxclients in httpd.conf to. You'll need to recompile Apache to increase that limit.

So even at httpd.conf setting is set to 150 it will still allow 256 clients?

Sorry, my explanation was bad. If you set it to 150, it will limit you to 150. If you set it to 256, it will limit you to 256. But if you set it to 500, you'll still be limited to 256. And so on.

Thanks. :)
