This is the umbrella JIRA for all the future HornetQ boot time optimization fixes.

I was measuring AS boot times today. Here are the results.

-----------------------
Test Configuration
-----------------------

 * AS TRUNK (https://svn.jboss.org/repos/jbossas/trunk -r 105792 default configuration)
 * Sun JDK6 (java version "1.6.0_20")

 * Intel Processor (Intel(R) Core(TM)2 CPU T7400  @ 2.16GHz)

Round 01  -  18s:379ms
Round 02  -  18s:399ms
Round 03  -  18s:837ms
Round 04  -  19s:274ms
Round 05  -  18s:506ms
Round 06  -  19s:102ms

Round 13  -  18s:855ms
Round 14  -  18s:545ms
Round 15  -  19s:210ms
-----------------------
Average   -  18s:743ms
-----------------------

-----------
Conclusion:
-----------

24s:840ms = 100 % AS trunk boot
18s:743ms ~  75 % AS trunk without HornetQ boot
---
 6s:097ms ~  25 % HornetQ boot
