You really need to do more research on your own: -Xms = set initial Java heap size -Xmx = set maximum Java heap size If you are currently allocating 1GB (-Xmx1024), then you probably want to set it to something /bigger/ than 1GB. Perhaps 1.5GB: -Xmx1536 Upon the recommendation of another poster, you might want to set the initial and the maximum to the same thing (that will allocate the entire Java heap at once, instead of forcing the memory manager to grow the heap during runtime): -Xms1536 -Xmx1536 It's up to you to decide what your heap size should be. You need to understand the operation and needs of your application, as well as pattern of usage by your users to choose a good heap size. You can certainly allocate a HUGE heap and cross your fingers, but that is not always a good strategy -- especially when you are limited by physical RAM as well as the other processes running on your server. Hope that helps, -chris
