Enhancing Performance

For those Plesk administrators who want to use Plesk more efficiently,
we propose ways to improve Plesk functioning in different situations. In
this chapter, we will discuss the following improvements:

• Reducing resources consumption for Plesk installations that operate
  in virtual private server environment.
• Increasing the number of domains that a single Plesk server is
  capable of managing.
• Preventing server overload by limiting the number of anti-spam
  processes.
