jlaunch.exe consuming more memory !

Hello,

I am in to the system preparation phase in solution manager . When i tried to sync up SLD and LMDB, jlaunch.exe starts consuming more memory which i checked in the task manager and also in resource monitor because of that the system lags its responsiveness .This same thing happened for our previous solman server which had 4GB RAM so we thought because of the ram we had this issue so we scraped it out and installed a fresh solman server with 8GB RAM but now also we are facing  the same issue.            

The following are the java parameters:
