JLBHOptions

public JLBHOptions()

Method Detail

throughput

@NotNull
public @NotNull JLBHOptions throughput(int throughput)

Number of iterations per second to be pushed through the benchmark

Parameters:

throughput - defaults to 10,000

Returns:

Instance of the JLBHOptions to be used in the builder pattern.

throughput

@NotNull
public @NotNull JLBHOptions throughput(int throughput,
                                                TimeUnit throughputTimeUnit)

Number of iterations per time unit to be pushed through the benchmark

Parameters:

throughput - defaults to 10,000

throughputTimeUnit - defaults to TimeUnit.SECOND

Returns:

Instance of the JLBHOptions to be used in the builder pattern.

latencyDistributor

public JLBHOptions latencyDistributor(LatencyDistributor latencyDistributor)

Allow the distribution to be altered pseudo-randomly

Parameters:

latencyDistributor - function to take the average latency and multiply it by a function.

accountForCoordinatedOmission

@NotNull
public @NotNull JLBHOptions accountForCoordinatedOmission(boolean accountForCoordinatedOmission)

Determines whether the start time is the time the event was supposed to have happened (i.e. accounting for co-ordinated omission) or whether the the start time is just the a factor of the throughput (i.e. not accounting for co-ordinated omission).

Parameters:

accountForCoordinatedOmission - defaults to true

Returns:

Instance of the JLBHOptions to be used in the builder pattern.

recordJitterGreaterThanNs

@NotNull
public @NotNull JLBHOptions recordJitterGreaterThanNs(int recordJitterGreaterThanNs)

Determines how much jitter to record.

Parameters:

recordJitterGreaterThanNs - Defaults to 1000

Returns:

Instance of the JLBHOptions to be used in the builder pattern.

recordOSJitter

@NotNull
public @NotNull JLBHOptions recordOSJitter(boolean recordOSJitter)

Determines whether or not to record jitter

Parameters:

recordOSJitter - Defaults to true

Returns:

Instance of the JLBHOptions to be used in the builder pattern.

warmUpIterations

@NotNull
public @NotNull JLBHOptions warmUpIterations(int warmUp)

Determines how many warmup iterations to perform. Note: warmup iterations are continuous.

Parameters:

warmUp - Defaults to 10,000

Returns:

Instance of the JLBHOptions to be used in the builder pattern.

runs

@NotNull
public @NotNull JLBHOptions runs(int runs)

Number of runs of the benchmark

Parameters:

runs - Defaults to 3

Returns:

Instance of the JLBHOptions to be used in the builder pattern.

iterations

@NotNull
public @NotNull JLBHOptions iterations(int iterations)

Number of iterations of the benchmark not including warmup.

Parameters:

iterations - Defaults to 100,000

Returns:

Instance of the JLBHOptions to be used in the builder pattern.

iterations

@NotNull
public @NotNull JLBHOptions iterations(long iterations)

jlbhTask

@NotNull
public @NotNull JLBHOptions jlbhTask(JLBHTask JLBHTask)

Returns:

Instance of the JLBHOptions to be used in the builder pattern.

pauseAfterWarmupMS

@NotNull
public @NotNull JLBHOptions pauseAfterWarmupMS(int pauseMS)

Option to set a pause after the warmup is complete

Parameters:

pauseMS - pause in ms default to 0

Returns:

Instance of the JLBHOptions to be used in the builder pattern.

skipFirstRun

@NotNull
public @NotNull JLBHOptions skipFirstRun(boolean skip)

Option to skip first run from being included in the variation statistics.

Parameters:

skip - default to true if runs greater than 3

Returns:

Instance of the JLBHOptions to be used in the builder pattern.

jitterAffinity

@NotNull
public @NotNull JLBHOptions jitterAffinity(boolean jitterAffinity)

Should the jitter thread set affinity or not

Parameters:

jitterAffinity - default is false

Returns:

Instance of the JLBHOptions to be used in the builder pattern.
