php-fpm and request_slowlog_timeout granularity

Hi,
I have a joomla-5.4.0 system on fedora43 with php-8.4.17 and a few of the
modules we have running take about 600ms to load. This brings it under the
php-fpm slowlog threshold, removing any ability for us to better identify
what functions are consuming so many resources.

What other options do I have outside of a php debugger or profiler?

Any suggestions greatly appreciated.

Thanks,
Alex
