Comment (by Hristo Sg):

 Here are the performance test we've done so far:

 CPU - Total number of CPU-seconds that the process used directly (in user
 mode), in seconds.
 MaxRSS - Maximum resident set size of the process during its lifetime, in
 Kilobytes.

 PHP 7.0 - no imagick loaded - MaxRSS: 93261 CPU user: 0.0204
 PHP 7.0 - imagick loaded - MaxRSS: 118094 CPU user: 0.0742
 PHP 7.1 - no imagick loaded - MaxRSS: 50444 CPU user: 0.0144
 PHP 7.1 - imagick loaded: MaxRSS: 82350 CPU user: 0.0678
 Curl requests to phpinfo comparison (1 request per second - 5 min):
 PHP 7.0 (no imagick)- Average response time: 0.071818 ms |Number of
 requests: 300
 PHP 7.0 (with imagick) - Average response time: 0.143573 ms |Number of
 requests: 300


 Performed tests and added results for PHP 5.6
 PHP 5.6 - no imagick loaded - MaxRSS: 60400 CPU user: 0.019
