Site opens too late. Can anyone help?

Delete all your plugins. Check your website after that. Reinstall only the needed plugin one by one and check your performance. This way you will find the one that is causing the problem
 
Yeah I can agree with @mystique07 . And one more thing: once you re-installed the plugins needed don't forget to update them regularly. Older versions can be more vulnerable!
 
This looks like core WordPress files and commands are compromised. Backup your files and data and reinstall WordPress and the plugins & themes.
