Memory usage by application, class, and method

You can use EsMemoryUseReport to determine the size of the code in an application. For example, to report the memory usage by the CPM application, use the following:

EsMemoryUseReport new

sortByTotal: true;

showMethods: false;

reportMemoryUsedBy: CPM

This example produces output on the Transcript similar to the following:

Application: CPM

Class Storage Methods ByteCodes Literals Total

------------------------------------------------------------------------

Process 10328 73 2384 484 13196

ProcessorScheduler 6640 40 1800 276 8716

Delay 4220 28 1096 220 5536

EsQueue 3400 20 1108 308 4816

UIProcess 1868 9 336 32 2236

Semaphore 1552 7 276 0 1828

EsLongArray 512 0 0 0 512

------------------------------------------------------------------------

Application Total 28520 177 7000 1320 36840

The numbers are in bytes. The columns have the following meanings:

Storage

Indicates the memory used by the class definition itself.

Methods

Contains a count of the number of methods in the class.

ByteCodes

Contains the bytecode size for all the methods in the class.

Literals

Contains the size of the literals for all the methods in the class.

Total

Contains the total of the class. This is the sum of Storage, ByteCodes, and Literals.

EsMemoryUseReport can report more detailed memory usage be setting showMethods: to true. This produces a report with the class information as shown above, but also reports memory statistics for each method in the class.
