Agispeedy - faster than AGI and performance improved 10 times comparing with AGI

 

The Agispeedy is robust implemention of AGI in asterisk. Agispeedy is inconceivable faster than AGI. The result of test shows that by using Agispeedy in asterisk, the performance of system would be improved more than 10 times comparing with AGI.

Agispeedy Features:

* implemention of AGI(FastAGI) over TCP Sockets 
* Work in Stabilize Prefork Mode and Written by Pure Perl. 
* Easy to Maintain, unlike FastAGI(Dynamic Load AGI no need restart Agispeedy services) 
* Providing possibility of running AGI on a remote server(Inheriting the FastAGI) 
* Fast Database Connect(system can hook database connection in child process)

Table of asterisk extend tech:

 

name	speed	reliability	cluster
asterisk module	top faster	easy crash	no
agi	slowly	strong	no
fastagi	faster	maybe crash	yes
agispeedy	faster	strong	yes

how does agispeedy work

example : 
exten => 123456,n,AGI(agi://127.0.0.1/demo_dynamic?number=7890)

* asterisk send socket request scriptname demo_dynamic with args 
* agispeedy get one child to response asterisk 
* child find demo_dynamic static module in memory 
* child find demo_dynamic.dam in /agispeedy/var/ 
* child do args parse and push to hash table 
* child synatx checking and complie demo_dynamic.dam 
* child run entry function demo_dynamic() 
* child exit
