海外TECH	DEV Community	The Best Garbage Collection for JMeter	https://dev.to/qainsights/the-best-garbage-collection-for-jmeter-99h	The Best Garbage Collection for JMeterThe Best Garbage Collection for JMeter Automated memory management is one of the core features of Java By default JMeter uses the GGC algorithm to clean up the unreferenced objects in the heap GC algorithms have been evolving for the past many years In this blog article I have done some experiments using the various GCs in JMeter to identify which GC algorithm yields us more threads to run in a bare metal medium powered laptop Before getting started I am sure that some of you may not agree with the environment setup to validate the GC base lining the maximum number of threads using the load model etc If you are not satisfied with this setup please share your comments so that I can learn along with you I am not going to bore you with the formula to come up with the maximum number of threads that we can inject Instead let us focus on the experiment This experiment s GitHub RepoBack to basicsWhat is Garbage Collection In Java everything is an object Object needs a place to live and it will be huge When you start the Java application your Java Virtual Machine creates new objects in the Young Generation which is expected to be short lived But sometimes objects will live longer and takes up the heap space  The longer the object lives it is likely to become garbage collected in the Old Generation Watch the phrase it is likely JVM may clean up the unreferenced object or it may not It is up to JVM s decision So what is an unreferenced object If the object has a reference in the stack memory then it will not be garbage collected Else it might be garbage collected Above example is from the GGC perspective at least at a high level If you want to learn more please check my Performance Engineers playlist on YouTube Types of Garbage CollectorsWithout deep diving into the GC algorithms let us see the high level overview about the following types of Garbage Collectors in Java  Serial Garbage CollectorParallel Garbage CollectorCMS Garbage CollectorG Garbage CollectorEpsilon Garbage CollectorZ Garbage CollectorShenandoah Garbage CollectorIn this experiment I did multiples execution using commonly used GC algorithms namely GGC Z GC and Shenandoah GC Serial GC is one of the simplest GC algorithms  It uses single thread to carry out the GC activity It is not ideal for multi threaded application like JMeter Parallel GC uses multiple threads to carry out the GC activity but it injects the pauses while doing the GC CMS Concurrent Mark Sweep GC is deprecated algorithm in Java where it marks the referenced object and sweeps the remaining It needs more CPU to achieve more throughput Since it is deprecated I have not included this GC for the experiment Epsilon GC is a passive GC Meaning it will not perform any GC Once the heap is full It just terminates the application It is useful to baseline the configuration and for testing your application Hence I am not using Epsilon GC in this experiment Epsilon GC Meme by NaveenKumarFor more memes please check this repo GGC Garbage First Garbage Collector is one of the commonly used GC algorithms in Java and it is the default GC in Java It separated heaps into multiple regions as I mentioned above and carry out the GC activity efficiently GGC is performant than CMS GC ZGC yields less than ms GC time It performs all the expensive work concurrently ZGC yielded surprising results in this experiment It works well with the large volume of heaps Shenandoah GC is from Red Hat team which the low pause time garbage collector that reduces GC pause times by performing more garbage collection work concurrently with the running Java application Whether your heap size is  GB or GB the semantics is identical Experiment SetupI have not used Docker setup to run these tests I want to measure the performance of each GC for JMeter in a bare metal machine My laptop is at least six years old But it is running great apart from fan speed Below is the system configuration OS Name Microsoft Windows ProSystem Model Inspiron System Type x based PCProcessor Intel R Core TM i U CPU GHz Mhz Core s Logical Processor s Installed Physical Memory RAM GBJava and JMeter versions are as follows Java version for GGC and Shenandoah is Java AdoptOpenJDK with Hotspot JVMJava version for ZGC is Java AdoptOpenJDK with Hotspot JVMJMeter No JMeter pluginsMax heap size allocated is GB for all the experiments Demo application set up Jetty v hitting sample demo application at localhost JMeter Test PlanTotal number of HTTP Samplers Constant Timer of millisecondsTotal Bytes for all the requests KilobyteBefore I started the experiments I have closed all the resource consuming programs such as Vivaldi browser MS Outlook One Drive Docker MS Office programs recording software and more I have kept only the following programs open Two terminal sessions to run Jetty application and JMeter in CLI mode Notepad to take notes Snagit to capture the screenshots Task Manager to view the CPU and Memory trends Of course there will be background processes running e g Anti virus daemon apps etc I cannot kill those Following are the assumptions we can make of RAM i e GB is for Operating System GB is allocated to JMeter which is consistent across the multiple runs GB might be allocated for the daemon threads We are making use of GB of RAM slice Remaining might be consumed by Jetty app No network overhead as we are using locally hosted app From JMeter perspective there is no resource consuming elements in the test plan Also after each run I gave some breath time for my system so that it can come back to normal utilization How to change the heap size in JMeter Open jmeter bat in your favorite editor and edit the line which has SET HEAP and configure the heap size to g e g set HEAP Xmsg Xmxg XX MaxMetaspaceSize mThe Best Garbage Collection for JMeter ExperimentGGCI started my experiment with GGC as it is the default GC in Java and with threads with a ramp up of seconds I am aware that this number is high considering my system configuration But surprisingly it performed well Throughout this experiment I am focusing only on the number of threads that JMeter can inject  Jetty will throw high response time eventually The response time number of failed transactions and other parameters are secondary for this experiment But in your actual project you need to consider all the parameters Below is the threads GGC screenshot It is a clean run For every run I terminated the execution after few minutes of ramp up GGC ThreadsNext run I injected threads which is also performed well But it threads run I started seeing failures as shown below GGC ThreadsIn and threads run as well the trend persisted After these runs I injected because of over confidence But surprisingly th thread JMeter threw Out of Memory heap space error To know more about this error please check my YouTube tutorial GGC ThreadsI repeated the same run the outcome is similar Let us conclude GGC experiment stating that JMeter could inject around threads in my system configuration Shenandoah GCTo change the GC algo in JMeter open jmeter bat and add the below in set GC ALGO line XX UseShenandoahGCAs we know Shenandoah GC should perform better than GGC Let us see the Shenandoah GC results I started my first test with the over confidence by injecting threads Shenandoah GC handled well Here is the screenshot Shenandoah ThreadsThen I increased the thread count to It broke at th thread with heap space out of memory error If you see the error count it is surprisingly less Shenandoah ThreadsZGCTo change the GC algo to ZGC open jmeter bat and add the below in set GC ALGO line XX UseZGCHere comes the next surprise I started ZGC with threads My bad See it for yourself It threw heap space out of memory after threads I am not sure why If you are expert in ZGC please share your inputs in the comment section ZGC Even for threads I got out of memory error again ZGC OOMBut it ran well for threads As the ZGC threw OOM for threads I did not purse my experiment further ObservationsGGC injected more than threads without any issue But there were some stutters during the execution I am not sure is it because of my OS or JMeter I should have executed with Visual VM but I do not want to have overhead again GGC had lot of errors in the samplers consistently across high volume runs Shenandoah GC handled the load well The number of errors were less observe the trend in the above screenshots you can easily correlate Response times were high From my perspective I never bothered about that My focus is only on active threads I expected much from ZGC but it ran out of memory too soon Maybe it needs more slices to work with But clearly ZGC is not apt to run high volumes test If you can carry out this experiment in a high powered instance in cloud you can begin with ZGC by slicing more memory into it I can hear you saying that why you have not tuned the GC parameters to yield performance My intention is to try just vanilla flavors without touching the other parameters The main reason is there are too many parameters to begin with E g Shenandoa GC has three modes normal satb iu and passive Default is normal satb Tuning these parameters might have yielded more number of threads If you take GGC we could have achieved more performance I am not a tuning expert Let me conclude the experiment here ConclusionFrom multiple runs with varying number of threads GGC and Shenandoah performs almost similar in terms of performance Further tuning of GGC might have outperformed Shenandoah GC and vice versa ZGC algo has failed in my system configuration But it could perform better in a better environment To choose the best GC you need to run your tests with each GC and baseline each number in your environment setup You will get surprising results as me	2021-07-06 20:08:16
