eAcc settings

[Elfz]

what settings do you guys use in a shared hosting environment?


My current setup:
extension="eaccelerator.so"
eaccelerator.shm_size="128"
eaccelerator.cache_dir="/dev/shm/eaccelerator"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="7200"
eaccelerator.shm_prune_period="1200"
eaccelerator.shm_only="1"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
eaccelerator.keys="shm_only"
eaccelerator.sessions="shm_only"
eaccelerator.content="shm_only"

I recommend using

eaccelerator.shm_size="16"
eaccelerator.optimizer="0"

16MB cache per process is enough as all cached scripts are shared in memory via /dev/shm/ .
do not use "shm_only" mode, it will not populate the on disk cache in /dev/shm.


You may need to load it as a zend_extension if ZendOptimizer is used.

What do you mean by per process? I thought that value is the size allocated to cache scripts. 16MB can be filled up quickly. And why disable eaccelerator.optimizer?

 

[mistwang]

when use PHP suEXEC, each PHP process will create its own cache memory as each process was started independently.
If you use ZendOptimizer, you should turn off eaccelerator's.

I don't see any instances of zend_extension in php.ini but it shows Zend in php version.

Zend Engine != ZendOptimizer
