Simplified Saaze Monitored with PHPSPY
This blog uses the PHP-based Simplified Saaze software. I measured Simplified Saaze using XHProf:
Still I am interested whether I missed anything.
In multiple talks Rasmus Lerdorf, the creator of PHP, advertises PHPSPY.
PHPSPY was written by Adam Saponara. The source code is in GitHub: https://github.com/adsr/phpspy.
I ran PHPSPY in top mode for some days using the dynamic mode of Simplified Saaze: phpspy -p 940 -p 17132 -p 61898 -p 61899 -t. The output is below. Some remarks on inclusive and exclusive times or counts:
- Inclusive counts everything for the function and all its function it calls.
- Exclusive only counts a particular function.

Interestingly, the time spent by Composer-classes is greater than the actual runtime of Simplified Saaze!
Added 11-Dec-2023: Measured once again. Results are below.

Results are similar. Clearly even more accentuating the importance of Composer.
Added 08-Feb-2024: I had some trouble getting PHPSPY to work again, see phpspy no longer works #136. I ran PHPSPY again but this time I dropped composer, which was marked as dominant in above PHPSPY sessions. Results for three days are as below.

Eliminating composer indeed cut away all composer related CPU usage.
It looks that above run cannot be fully compared to the two previous runs.
This time FFI::string became dominant, which was not dominant in previous runs.
No PHP source code from Simplified Saaze is visible except Saaze\TemplateManager::<main>.
Instead string-processing, like substr(), str_replace(), and strpos() seem to be important.
I am still hesitant how much I can trust above run as the err_count is so alarmingly high.
Added 12-May-2024: Another measurement with phpspy, this time with MD4C used as an extension, i.e., no FFI.
Watch out for the very high error count.
It is remarkable that the max() function is so dominant.
