adding think time in jmh

[Sarath Babu]

Thanks for your Quick response.
I want to give *think time* between each thread request in below test case,
Is there any option ?

        @SuppressWarnings("unchecked")

@Benchmark

@BenchmarkMode({ Mode.*SampleTime* })

@OutputTimeUnit(TimeUnit.*MILLISECONDS*)

@Warmup(iterations = 3)

@Measurement(iterations = 10)

@Threads(value = 50)

*public* *void* measureCacheUpdateWithEagerConfig(EagerCachePut cPut,
RandomNumberBelowThousand rNum) *throws* InterruptedException {

cPut.cache.put(rNum.key, AccountUtil.*accountUpdate*(rNum.key));

}


        @State(Scope.*Benchmark*)

*public* *static* *class* EagerCachePut {


*public* CacheManagerImpl impl;

@SuppressWarnings("rawtypes")

*public* Cache cache;


@Setup

*public* *void* setup() {

impl = *new* CacheManagerImpl();

cache = impl.getCache("lowUnitsAccountEagerDistributedCache");

cachePutAccountObjects();

}


@SuppressWarnings("unchecked")

*public* *void* cachePutAccountObjects() {

*for* (*long* i = 1; i <= 1000; i++) {

cache.put(i, AccountUtil.*getAccount*(i));

}

}


@TearDown

*public* *void* doTearDown() {

impl = *null*;

cache = *null*;

}

}




        @State(Scope.*Thread*)

*public* *static* *class* RandomNumberBelowThousand {


*public* *long* key;


@Setup(Level.*Invocation*)

*public* *void* doSetup() {

key = getRandomNumber();

}


@TearDown(Level.*Invocation*)

*public* *void* doTearDown() {

key=0;

}

*public* *long* getRandomNumber() {

*return* (*long*) ((Math.*random*() * (1000 - 1)) + 1);

}

}


Thanks,
Sarath
