input: Write a function to optimize a Flask application for efficient performance. The function should integrate Redis for caching, use uWSGI for application serving, employ gunicorn as the WSGI server, utilize Flask-Compress for compression, and make use of global variables and thread-local objects for better performance. Additionally, it should avoid direct SQL queries and prefer using model methods, and use query parameters in URLs instead of plain ones. 
  
  
  from flask import Flask, request, jsonify
  
  app = Flask(__name__)
  
  @app.route('/api/<endpoint>', methods=['GET', 'POST'])
  def process_request(endpoint):
      # Optimization techniques implementation
      use_redis_for_caching()
      use_uwsgi_for_serving()
      use_gunicorn_as_wsgi_server()
      use_flask_compress_for_compression()
      use_global_variables_where_applicable()
      dont_use_sql_queries_directly()
      use_query_parameters_in_urls()
      use_thread_local_objects_for_performance()
  
      return jsonify({"message": "Request processed successfully"})
  
  # Example assertions to check the function functionality
  assert process_request('/api/test')['message'] == "Request processed successfully"
  assert process_request('/api/another')['message'] == "Request processed successfully"
  assert process_request('/api/last')['message'] == "Request processed successfully"
