RANADEEP SHARMA commented on CXF-6938:
--------------------------------------

Hi Sergei,

Could you please comment your experiences on performance analysis of the module. I am sure
other users must have reported similar issues.
I am just trying to get some directions on how to narrow down the scope for trouble-shooting
since you guys developed the library.

Regards,
Ranadeep.

> We have an application with REST client components for making calls to Backend web services.
During our routine performance test, JProfiler tool shows lots of Bus property entries (with
keys named "bus.providers.set.<hashCode>") populated while creating instances of ClientProviderFactory.
> These Bus property entries seem to stay in heap for the whole duration of the 6 hour
run. In fact, around 100,000 entries occupying 13 MB of heap.
> In short, GC doesn't seem to happening frequently enough to keep the heap usage within
limits.
> Is this some sort of a bug or, lack of necessary configuration in CXF?
> Either ways, we need your guidance for trouble-shooting this issue.
