Home -> Community -> Mailing Lists -> Oracle-L -> RE: Stored procedure performance
There are many many answers to your question. And it all lies in what your trying to accomplish.
As a general rule, packages perform better than procedures are the entire
package is loaded.
PL/SQL is slower than SQL in due to the context switches and "calls" to sql
parser, although these can be minmized by using bulk transactions and other
features.
Java procedures out perform plsql when it is heavily computational.
PL/SQL out performs Java procedures when it is heavily transactional
OCI calls being one of lowest levels are of course very efficient.
The performance differences can be milliseconds or it can be hours depending what is trying to be accomplished.

In the process of making a design decision, I'm looking for information on the relative performance of PL/SQL stored procedures / packages vs. both Pro*C / OCI SQL calls and Java stored procedures. All things being equal, let's say for DML calls with little or not procedural logic, what technique is likely to yield the best performance, and how much of a performance difference exists? In the case of PL/SQL vs. SQL, is the advantage of centralization overshadowed by a performance hit? In the case of PL/SQL vs. Java, is the advantage of a more "standard" and widely-used language among application developers similarly negated by a performance disadvantage?
I'm interested in hearing opinions based on both theoretical and empirical information. Thanks.
