It's completely normal for physical memory to be nearly 100 percent at all times, unless you have memory available that greatly exceeds the size of your index and any other data used by programs on the server. This is simply how operating systems work. http://en.wikipedia.org/wiki/Page_cache JVM memory usage is highly variable and will fluctuate all over. Do a Google image search for 'JVM sawtooth' to see how memory usage graphs within the JVM. Thanks, Shawn
