My apc.mmap_file_mask path is set to /tmp/apc.XXXXXX But on my hosting, my /tmp/ is very small, only about 2gb. My APC works very hard and those 2gb will be filled on about 1-2 days, until i restarted my HTTPD On the other side my /home/ is very big and very vacant, my usage there is only 2% My hosting said both of my /home/ and /tmp/ are on same disk, so they say there is no difference about speed. Instead of resizing disk partition (/tmp/), i was thinking about moving apc.mmap_file_mask to /home/. Can i move my apc.mmap_file_mask from /tmp/apc.XXXXXX to /home/ such as /home/apc/apc.XXXXXX/ ? Thanks.
