Configuring the kCluster

Set -Xk to handle objects up to the specified size using the -Xk option:

-Xk maxNumClass

Here, maxNumClass specifies the maximum number of classes the kCluster can contain.

-Xk instructs the JVM to allocate space for maxNumClass class blocks in kCluster. The GC trace data obtained by setting -Xtgc2 can help provide a guide for the optimum value of the maxNumClasses parameter. You must keep -Xtgc2 enabled until memory fragmentation is satisfactory.
