[resteasy-dev] Caching of ResteasyUriInfo in org.jboss.resteasy.plugins.server.servlet.ServletUtil

[John O'Hara]

During a benchmark run, we are seeing over 5% of cpu time taken up by each
request creating a new ResteasyUriInfo instance. Please see the attached
graph.

For most use cases in our application, the parameters are the same between
requests, and therefore the ResteasyUriInfo are immutable and could be
shared. The case that I can see where sharing a ResteasyUriInfo would be
problematic is when there are path parameters in the URI.

Could it be possible to cache ResteasyUriInfo that are immutable, or even
cache a URI with placeholders for URI that contain path parameters?

IIRC hibernate has a similar caching mechanism for prepared statements with
parameters, a similar approach may work here.

Thanks,

John
