Re: [weld-dev] [cdi-dev] microbenchmark for CDI performance
by Jozef Hartinger
Btw I've run your benchmark locally and observed the following results:
OWB 1.2.6: 9827ms
Weld 2.2.5.Final: 20ms
;-)
I did however tweak the test a bit so that Weld's optimizations can be
leveraged[1]. I admit that in certain situations (like your test without
my change) Weld performs worse than it should and this is a good input
for us.
As for the NPE you observed not sure what is going on there. Perhaps
WeldContextControl implementation in DeltaSpike is not really thread safe?
