What exact version of Weld 2.2.0 do you use? Can you describe your test application little bit more (number of beans, injections, decorators, etc)? Are these results from single measurement or is it some average?
Also, which type of bean-discovery-mode do you use ("all" is the default one). Do you use Jandex?
There is a test application, I am testing directly in company ERP system to work.
Number of beans: 250.
Number of interceptors: 3.
Result is average of 1000 runs on different machines
Weld 2.2.0 RC1.
Using jandex 1.1
