You can see the default values for PHP via Plesk and/or by using PHP Info.

Default settings can be adjusted upon request but performance settings can only be increased so far due to the nature of shared hosting.

  • memory_limit
  • max_execution_time
  • max_input_time
  • post_max_size
  • upload_max_filesize
  • opcache.enable
  • disable_functions

  • session.save_path
  • mail.force_extra_parameters
  • open_basedir
  • error_reporting
  • display_errors
  • log_errors

For WordPress sites, there are options for plugins that break the files into smaller pieces, and the use of CDNs, SecureFTP, also provide alternatives.
