By default, performance settings for IIS application pools are the following:

• The maximum number of worker processes - 1
• Maximum CPU usage (%) - Unlimited

Check that the server has sufficient CPU resources. Limit maxInstances parameter in
Domains > example.com > PHP Settings and set maxInstances to 1.
