Are you restarting the services i.e. Apache/PHP-FPM between each test?
A: No - The server is a shared hosting server - I have no control over restarting services. The issue is demonstrated by changing the PHP version in the CPanel using MultiPHP Manager - as many times as you like!
I did a compare between the PHPInfo from PHP8.0 and PHP8.1 and found the following that might have an impact.
As I really don't understand these parameters very well, could you suggest any which may have an impact that I could change? (Not sure how well a text only email will format this, but here we go!):
Parameter PHP8.0 PHP8.1
Loaded Configuration File path error in 8.1?
allow_url_fopen Off On
display_startup_errors Off On
Expose_php Off On
Log_errors On Off
Mail.aff_x_header On Off
Max_execution time 600/30 600/600
max_input_time 120/60 120/120
memory_limit 1024/128 1024/1024
output_buffering no value 0
post_max_size 512/2 512/512
variables_order GPCS EGPCS
zend.assertions -1 1
PDO drivers Additional PDO drivers seen
PDO_ODBC section No PDO_ODBC PDO_ODBC section
Pgsql section in 8.1 No Pgsql Pgsql section
session.cookie_httponly no value 0

Hi Steve
Seems from the list above that the php.ini is not being loaded for v8.1
(I presume it shows a path for v8.0?) - to truly test side by side then
ideally both versions should be loading the same php.ini settings. You
should raise this as an issue with your hosting provider and once
resolved try your tests again
Some links below indicate that v8.1 *should* be quicker than v8.0:-
