GPerf Using Jesque
- 1. Jesque In Action gperf framework
- 2. Why? Easy Job Configuration Low Latency Redis is Fast Cache NoSQL Queue
- 3. And... Phase 2: Redis & Jesque
- 4. And... Phase 2: Redis & Jesque
- 5. Creating Jobs perf { runners { largeNumberPerformanceRunner { description = 'Large Number Performance Test' maxWorkers = 20 workerClass = com.perf.runners.math.LargeNumberPerformanceService } } } class LargeNumberPerformanceService extends AbstractPerformanceService { Result performTest() { Long result = 1 def executionTime = benchmark { 100000.times { result += it } } new SimpleResult(testName: 'Long Number Performance Service', executionTime: executionTime) } }
