This has been discussed previously, and was assumed to be handled by PHP automatically: https://github.com/silverstripe/silverstripe-framework/issues/2739#issuecomment-32603005 It’s unclear if its a regression in SS4. Tested with PHP 5.6.29, by setting xdebug breakpoints and inspecting memory_get_usage() before and after GDBackend->manipulateImage(). Even a single 7MB JPEG straight from my DSLR (6000x300) can chomp bring the system from 30MB to >128MB memory use. That’s in addition to the 7MB of PHP memory required for the $content variable. Note that the image manipulations likely happen on the raw bitmap, which is much larger than the 7MB compressed JPEG. Checked ImagickBackend, which doesn’t have this issue (and only uses about half the memory for the same set of images). |
