@anon77445132 Deactivating the opcache-module results only in slower overall performance of execution of kirby.
@lukasbestle As mentioned in my post from 2017-01-30 there seems to be a problem with the execution of call_user_func_array($function, $arguments) in toolkit/helpers.php. The calls results in slow “first time execution” for the image-objects. Maybe this is an PHP-internal effect?!
Theoretically, the execution of call_user_func_array() was optimized in PHP7, but in this case it is not faster.
As I have not enough PHP-knowledge, I’m not able to further investigate the specific calls, which are executed during getting/preparing an image.
