Alessio Soldano commented on CXF-6837:
--------------------------------------

May I ask if you could try your benchmark with a CXF version patched with 
CXF-6826 changes ? Last time I profiled this section of the code most of the 
time was spent on internally converting the media type strings to MediaType 
objects, which is what CXF-6826 addresses.

>          Components: JAX-RS
>    Affects Versions: 3.1.5, 3.0.8

>            Reporter: Neal Hu
>             Fix For: 3.2.0

> CXF selects the msgBodyReader/writer in the reader/writer list for every 
> request, which has big impact to the performance. Jersey also has the cache 
> in 
> org.glassfish.jersey.message.internal.MessageBodyFactory._getMessageBodyReader(...).
>  I have tried add the cache for CXF in ProviderFactory and been proved that 
> it has improved 7-8% for json requests in JMeter. Please let me know if you'd 
> like me to add the enhancement for CXF. Thanks.
