Optimizing an application to reduce local memory usage. At least one executable class file of the application can be instrumented with analysis code, the executable class file including bytecode. The class file can be executed on a virtual machine, wherein during execution the analysis code generates data related to the application's use of local memory. The data related to the application's use of the local memory can be analyzed to generate a memory profile analysis. Based on the memory profile analysis, at least one portion of the bytecode can be automatically revised to reduce an amount of the local memory used by the application.
