performanceLog

public static org.apache.commons.logging.Log performanceLog()

get a reference to this logger so the log config happens in one place

Returns:

the logger

performanceTimingStart

public static void performanceTimingStart(String label,
 boolean multiThreaded)

add a performance timer

Parameters:

label - in config and refer to this

multiThreaded -

performanceTimingDelete

public static void performanceTimingDelete(String label)

add a performance timer

Parameters:

label - in config and refer to this

performanceTimingGate

public static void performanceTimingGate(String label,
 String key)

add a performance gate. This measures from start until now, not a duration

add a performance gate for all performance timers, for a duration from start to finish. Cannot overlap. Will count all and keep a count if more than 1

Parameters:

key - something that will end up having _durationMs on end

durationNanos -

performanceTimingDuration

public static void performanceTimingDuration(String label,
 String key,
 long durationNanos)

add a performance gate for a duration from start to finish. Cannot overlap. Will count all and keep a count if more than 1
