Simple PHP benchmark comparison between official PHP 8.2 image and SUSE's SLE-BCI:PHP8.2.
Using the bench.php script provided at https://github.com/sergix44/php-benchmark-script
For both images, I set the memory_limit variable in php.ini to 1GB and call the bench.php script with a multipler of 10x (runs the tests 10 times in a row). For SLE-BCI, I installed the additional packages: php8-ctype php8-iconv php8-tokenizer For PHP 8.2, I installed the zip extension (required by one of the benchmarks).
# docker build official -t ericosuse/phpdemo-official:latest
# docker build sle-bci -t ericosuse/phpdemo-slebci:latest
Official PHP 8 image can be found here: https://hub.docker.com/_/php SLE-BCI image can be found here: https://registry.suse.com/repositories/bci-php
For the official PHP 8.2 image:
# docker run -it ericosuse/phpdemo-official

Even though the timings are almost the same for both, SLE-BCI offers slightly faster I/O and random number generation, beating the official image by almost 2 seconds. The size of the images, however, are VERY different:
