(In reply to Eric Schirra from comment #10) > The flag Xmx specifies the maximum memory allocation pool for a Java Virtual > Machine (JVM), while Xms specifies the initial memory allocation pool. As I think, this line is obsolete, I changed it to: # set_option "-Xms128M -Xmx1G" It is working fine and I guess it is working little faster. Maybe it is only wishful thinking. Further on I will work with this changing .
