Why there's two users exist for apache? and is it giving impact to free memory? root has a lot of apache instance & www-data too.

While I want to decreasing the MaxServer configuration into 5 on apache.conf and I get suprise while seeing the top report.

I am using mpm-itk for the apache.

Could you please enlight me. Thank you.

I found the answer:

That's the way how mpm-itk works by creating child process with user and group whom assigned on virtual host. It make perfomance hit. I am going back to mpm-prefork.
