Cache URITemplates instead of creating them over and over resulting iâ¦
â¦n wasted CPU cycles and GC runs. The cache prevents having to compile
java.util.regex.Pattern when the underlying templates seldom change as well as
preventing other fairly heavy lifting each time a template is instantiated.
My load tests show approx 10% throughput increase on a basic JAX-RS service
with 10 client threads in JMeter. My use case uses a lot of URITemplate
instantiation due to calling javax.ws.rs.core.UriInfo.getMatchedURIs() on each
sub-resource call.
I checked that URITemplate is thread safe and hence viable to be used in an
instance cache without the need for additional locking.
