Hi Internals

I wondering if "apc.slam_defence" and "apc.write_lock" should be turned 
on at the same time?

The default for APC v3.1.13 have both settings turned on.

But the documentation says "apc.slam_defence is Deprecated by 
apc.write_lock."

http://www.php.net/manual/en/apc.configuration.php#ini.apc.slam-defense

So I'd like to know how should the settings be configured?

Thanks

from a quick look and based on the documentation I think that the default
values should be changed as there is no reason to have the slam_defense
enabled, and on a related note the docs refer to this section as
slam_defense being an integer which controls a percentage (so valid values
are between 0 and 100) while the code seems to parse and store this as a
boolean value.
could somebody look into this and clarify the docs maybe?
