All Implemented Interfaces:

EventHandlerIF, SingleThreadedEventHandlerIF

public class ReplaceMicroBenchmark

extends Object

implements SingleThreadedEventHandlerIF, EventHandlerIF

The ReplaceMicroBenchmark reports the results of a simple microbenchmark that performs a number of replace operations on a single data object. The benchmark initializes, creates a single object, appends a specified amount of data to the object, and then begins the benchmark. The benchmark operates in two phases, an initialization phase and a test phase. The two phase perform identical operations. Operations during the initialization phase are not, however, measured. The initialization phase serves to warm the caches, remove JIT irregularities, etc.. During each phase, the benchmark pauses a user-defined period and then submits and update. The user may define an additional pause inter-phase pause period. During the test phase, the benchmark records the time elapsed between the dispatch of the update to the receipt of the result of the update.

Initialization Parameters: The ReplaceMicroBenchmark is controlled by a number initialization parameters. These parameters and their result are described below.

InitLength

The number of operations to perform during the initialization phase.

InitPauseTime

The amount of time (in milliseconds) to pause before submitting an update during the initialization phase.

SettleTime

The amount of time (in milliseconds) to pause between the initialization phase and the test phase.

TestLength

The number of operations to perform during the test phase.

TestPauseTime

The amount of time (in milliseconds) to pause before submitting an update during the test phase.

DobjSize

The size of the data object on which the benchmark will be performed.

ReplaceSize

The number of bytes to modify in each update.
