Very slow debugging in Eclipse

I try to debug Jonas webapp under Eclipse. Unfortunately when I connect to the remote application everything works terriblly slow (also after killing all java applications and restarting the PC). I use also JRebel. What might be the cause of such behaviour?

Recently i was having extreme slow performance debug, both in eclipse and visual studio code.

In my case, the problem was with lombok configuration in JPA entities.

I changed the @Data anottation to @Getters and @Setters.

Looks like hashCode() and equals() implementantion of lombok was in conflict with JPA.

You could also try using the Java Monitoring and Management Console. This may help show where the "slowness" is. Keep an eye on the garbage collector and how much time the JVM is spending dowing garbage collection.

I changed values of -XX:MaxPermSize, -Xms and -Xmx parameters in eclipse.ini and it helped.
