I have had a similar issue for a couple of months now, I enhance at build time, also checked that the classes are persistence cable. Still runs like a dog, a couple of minutes to retrieve a few thousand records is par for the course.
I a not sure what started it, things were much better up until a couple of months ago and even reverting back to an old source version didn't fix it. Tried different servers and even blew away my DB and started again. I can use standard SQL to retrieve the same data in milliseconds. Turning on TRACE logging to trouble shoot it slows it down significantly more so it's a catch 22.

Enhancing at runtime might be OK to start learning as it quicker to start coding but it comes with lots of problems and limitations. I would say enhancing at build time is not an option for any serious developments. Finally, enhancing at build time is only a matter of one simple ant task, so there are no excuse :-) You can use that macrodef I setup for my project : macrodef is really (really really) powerfull ant concept. <macrodef name="enhance" description="This will enhance annotated Java entity classes."> <attribute name="class-dir" description="The class folder where to find .class file annotated and enhanced using OpenJPA"/> <attribute name="persistence-xml-file" description="The full path to the persistence.xml file"/> <attribute name="lib-dir" description="Folder where to find /openjpa and /jpa folders that contains all the .jar"/> <sequential> <taskdef name="openjpac" classname="org.apache.openjpa.ant.PCEnhancerTask"> <classpath> <fileset dir="@{lib-dir}"> <include name="**/*.jar"/> </fileset> <pathelement location="@{class-dir}"/> </classpath> </taskdef> <openjpac> <config propertiesFile="@{persistence-xml-file}"/> <classpath> <fileset dir="@{lib-dir}"> <include name="**/*.jar"/> </fileset> <pathelement location="@{class-dir}"/> </classpath> </openjpac> <mkdir dir="@{class-dir}/META-INF"/> <copy todir="@{class-dir}/META-INF" description="Copy persistence.xml to META-INF" overwrite="yes"> <fileset file="@{persistence-xml-file}"/> </copy> </sequential> </macrodef> To use that macro : <target name="enhance-build"> <echo message="Enhancing build ..."/> <enhance class-dir="${build-class-dir}" persistence-xml-file="${persistence-xml-file}" lib-dir="../lib"/> <echo message="Enhancing build complete."/> </target> Hope this helps.
