Optimize PHP on NetBSD

On a NAMP (NetBSD, Apache, MySQL, PHP) server, you can get a faster PHP rendering using eAccelerator.

First of all, install the php53-eaccelerator package.
Then, configure PHP to use it and the system to allow memory allocation:

# vi /usr/pkg/etc/php.ini
(...)
extension=eaccelerator.so
[eaccelerator]
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.shm_only="256"
eaccelerator.debug="0"
(...)
# sysctl -w kern.ipc.shmmax=536870912
# vi /etc/sysctl.conf
kern.ipc.shmmax=536870912
# /etc/rc.d/apache restart

According to ApacheBench, the initial “Time per request” was 3 sec. Using eAccelerator, it goes down to 1.9 sec.
