+Use Vim to open php.ini again to enable opcache extension and configure its options and behavior.
+<code>
+cd /etc/php/8.1/apache2/
+vim php.ini
+</code>
+First, uncomment the 'zend_extension=opcache' option to load the opcache extension. Uncomment means to remove the leading semi-colon ";" at the front of the line containing ';zend_extension=opcache' which will enable this extension in php.
+<code>
+Before
+;zend_extension=opcache
+After (uncommented)
+zend_extension=opcache
+</code>
+Now, move down to the '[opcache]' section of the php.ini file and add the following configuration.  Basically, just find the appropriate line and uncomment the line by removing the leading ';' semi-colon. You can safely ignore the . . . lines in the code box below.
+<code>
+[opcache]
+...
+....
+.....
+opcache.enable = 1
+opcache.interned_strings_buffer = 8
+opcache.max_accelerated_files = 10000
+opcache.memory_consumption = 128
+opcache.save_comments = 1
+opcache.revalidate_freq = 1
+</code>
+Press ESC button to exit the INS mode of Vim and save the configuration by entering :w [enter], then exit by entering :q!
+Now restart the apache service to apply new changes using the command below.
+<code>
+sudo systemctl restart apache2
 </code>
