Thanks for answering.
Here are some more details
1. CloverETL engine version 2.5.4
2. Not sure what you call Clover Server ? We have designed the graphs using Clover Designer (plugin within Eclipse), then we take the generated graph files (.grf), put this on the linux server and run command line like this :
Code: Select all
java -Xms512m -Xmx6144m
4. Running the graph on the Java5 version within 1,5 hr was considered as correct performance as files treated are very large (973Mb in total) ; and this is running fine since years (almost 10 year) on the Java5 environment.
Any optimisation idea within Java7 is welcome.
