Apc Cache Use Only 32M Memory

Question

Here my config

extension = apc.so

apc.enabled = 1
apc.shm_size = 128M
apc.shm_segments = 1
apc.gc_ttl = 7200
apc.ttl = 0
apc.num_files_hint = 1024
apc.file_update_protection = 2
apc.max_file_size = 5M
apc.stat_ctime = 1
apc.mmap_file_mask=/tmp/apc.XXXXXX

apc.filter="-/usr/share/phpMyAdmin/.*"

APC INFO: APC Version 3.1.3p1 PHP Version 5.3.3 APC Host .._._ (mysite.com) (127.0.0.1) Server Software Apache/2.2.15 (CentOS) Shared Memory 1 Segment(s) with 30.0 MBytes (mmap memory, pthread mutex locking)

[ ~]# sysctl -p
net.ipv4.ip_forward = 0
net.ipv4.tcp_syncookies = 1
kernel.shmmax = 134217728

What i must do to increase APC memory?

Accepted Answer

Have a look at the manual: , ~~furthermore, note the difference between size and maximum size.~~

Answer 2

It seems , at least in my case , that for this to work I have to add it to apcu.ini found in mods-available php folder(depending on version used) like this :

extension=apcu.so
apc.shm_size = "64M"

Answer 3

I'll repeat the solution here (because it was listed as a comment of the accepted solution):

You might need to remove the "M" from the apc.shm_size configuration value. The number is expected to be in megabytes, and some php versions will fail to parse the value and revert to the default (30 or 32 MB) if the given value is not a number.
