Remove --plugins options from uWSGI configuration

- The --plugins options were removed from the uWSGI configuration because the plugins are already included when uWSGI is installed via pip. Specifying the plugins explicitly is unnecessary and can lead to errors if the plugins are not found in the expected locations. By removing the --plugins options, we rely on uWSGI's dynamic plugin loading mechanism, which ensures that the required plugins (e.g., python, http) are loaded correctly without the need for manual specification.

- Add performance options.
