In order to shorten the time that it takes to run the eGen process, I modify a couple settings in the gen.bat file.  They modify the memory that is used by the JVM.

• ms128m –> ms512m
• mx512m –> mx1024m

The full line in the gen.bat looks like the following:

%JAVA_PGM% -Xss1m -ms512m -mx1536m -Ddefault_path=%INI_DIR% -classpath %GEN_CLASSPATH% com.jdedwards.runtime.generator.Generator %1

NOTE: This is on a workstation with 2GB RAM running Tools Release 8.97 and the settings are what I use.  This is not a recommendation from Oracle.

Do you have any tweaks for the eGen process that you use?
