Oracle 11g advantages for performance

Question

Hello,
I am doing test of Client side result set cache on oracle 11 g rel2 ,O/S- RHEL
i am doing test as below on 2 Oracle 11g rel2 test servers on RHEL
one oracle 11g rel2 instance is used as server1,from other oracle 11g rel2 server2, i am running queries connecting to server1 through sqlplus,listener(tnsnames )
i run query few times without any client cache settings then
i have set init.ora paras for oracle 11g rel2 for client result cache,cache size/cache lag
i run the same query few times
in both the cases after each run i am noting statistics
select * from V$RESULT_CACHE_OBJECTS;
select * from V$CLIENT_RESULT_CACHE_STATS;
select * from gv$cpool_conn_info;
also autotrace,plan etc
but after using cache this views are getting poplulated ,autiotrace plan shows cache is used
but i cant see any improvement in performance after using client cache like speed,reduce network trip, etc
in fact without using cache/with no hint ,query executes faster
let me know if i am missing something,i believe sqlplus internally using OCI
thanks

I tested with custom code using java/jdbc thin driver ,connecting same as between 2 oracle 11g2 instance 1 as client other server,running code calling queries from client connecting to server

Unless you plan to provide the information ask for about what it is you are doing there really isn't any point in providing status updates that: you test this, you tested that. You made several statements about what you were doing

You say you are doing a bunch of things
But you don't post any of those results so we can see what it is you are looking at.
No one can comment on things they can't see.

You have to be using OCI for client side caching so if you use the Java thin driver but don't use OCI there won't be any cacheing. There also won't be any if it is not enabled or if the query has certain constraints as listed in the doc

Queries that are not Cached
There are queries that are not cached on the OCI client even if the result cache hint is specified. Such queries may be cached on the database if the server result cache feature is enabled (see Oracle Database Concepts, "SQL Query Result Cache" for more information). If a SQL query includes any of the following, then the result set of that query is not cached in the OCI client result cache:
•Views
•Remote objects
•Complex types in the select list
•Snapshot-based or flashback queries
•Queries executed in a serializable, read-only transaction, or inside a flashback session
•Queries that have PL/SQL functions in them
•Queries that have VPD policies enabled on the tables

This Oracle-Developer.net article author doesn't seem to have any trouble caching results.
