Server load - when to scream?

Hello,

I would like to know, what is a good server load to start thinking of an extra server? How do I know which processes are killing most of my system?

I can see a lot of processes floating by when using "top" , but generally I only see a lot httpd processes of about 1.00% CPU usage and below and mysqld processes of about 5% - 10% CPU usage...

My current server load is an average of about 0.75, with peaks to 1.50 ... should I be thinking of an extra server? Maybe an extra database server is an idea?

Please give me suggestions...

Thanks in advance,

Leon Mergen
