optimal php settings for cf6

Im having the following php settings

allow_url_fopen = On
allow_url_include = Off
display_errors = Off
enable_dl = Off
file_uploads = On
max_execution_time = 40
max_input_time = 60
max_input_vars = 1000
memory_limit = 512M
post_max_size = 32M
session.gc_maxlifetime = 1440
session.save_path = "/var/cpanel/php/sessions/ea-php72"
upload_max_filesize = 8M
zlib.output_compression = On

​

but despite that I have increased the mem limit I started seeing the file upload taking more time than before can someone confirm if this is related to the numbers above

Nothing there should have any affect on the TIME it takes to upload a file.
