PHP-APCu是否使用与为opcache定义的相同的内存池？

Question

According to the docs, APCu is still using the same configuration as for APC which includes defining the amount of memory to be used

apc.shm_size = 32M

But Opcache has it's own configuration for memory:

opcache.memory_consumption = "64"

Does the amount allocated to APCu come out of the total memory_consumption setting for Opcache? Or are they separate?

Answer 1

They are separate, because they are separate modules and so would not want to share memory space.

Since APCu now is only a data-cache (something opCache cannot do), you might not need as much space for APCu either - depending on how much data is being stored.
