Java is one of the most popular languages and it's very important to understand the performance of Java servers. Modern JVMs compile the Java code in runtime using Just-In-Time (JIT) compiler and such JIT compiled code runs very close to optimized native code in terms of speed.
When understanding performance, it's important to know how Java works and we can also measure the performance using key metrics like Throughput and Latency. After measuring the performance, we can use profilers to understand the application behavior and find performance bottlenecks.
In this session, we will look at how Java manages the memory and how it optimizes the Java code using JIT compilation. We will also look at how we can use the Java Flight Recorder (JFR) to profile the JVM and find performance bottlenecks.
Finally, we can look at how "Flame Graphs" can be used to identify the most frequent code-paths quickly and accurately.

Investing in GenAI: Cost‑benefit analysis of Dell on‑premises deployments vs....Principled Technologies
Conclusion
Diving into the world of GenAI has the potential to yield a great many benefits for your organization, but it first requires consideration for how best to implement those GenAI workloads. Whether your AI goals are to create a chatbot for online visitors, generate marketing materials, aid troubleshooting, or something else, implementing an AI solution requires careful planning and decision-making. A major decision is whether to host GenAI in the cloud or keep your data on premises. Traditional on-premises solutions can provide superior security and control, a substantial concern when dealing with large amounts of potentially sensitive data. But will supporting a GenAI solution on site be a drain on an organization’s IT budget?
In our research, we found that the value proposition is just the opposite: Hosting GenAI workloads on premises, either in a traditional Dell solution or using a managed Dell APEX pay-per-use solution, could significantly lower your GenAI costs over 3 years compared to hosting these workloads in the cloud. In fact, we found that a comparable AWS SageMaker solution would cost up to 3.8 times as much and an Azure ML solution would cost up to 3.6 times as much as GenAI on a Dell APEX pay-per-use solution. These results show that organizations looking to implement GenAI and reap the business benefits to come can find many advantages in an on-premises Dell solution, whether they opt to purchase and manage it themselves or choose a subscription-based Dell APEX pay-per-use solution. Choosing an on-premises Dell solution could save your organization significantly over hosting GenAI in the cloud, while giving you control over the security and privacy of your data as well as any updates and changes to the environment, and while ensuring your environment is managed consistently.
Workstations powered by Intel can play a vital role in CPU-intensive AI devel...Principled Technologies
In three AI development workflows, Intel processor-powered workstations delivered strong performance, without using their GPUs, making them a good choice for this part of the AI process
Conclusion
We executed three AI development workflows on tower workstations and mobile workstations from three vendors, with each workflow utilizing only the Intel CPU cores, and found that these platforms were suitable for carrying out various AI tasks. For two of the workflows, we learned that completing the tasks on the tower workstations took roughly half as much time as on the mobile workstations. This supports the idea that the tower workstations would be appropriate for a development environment for more complex models with a greater volume of data and that the mobile workstations would be well-suited for data scientists fine-tuning simpler models. In the third workflow, we explored tower workstation performance with different precision levels and learned that using 16-bit floating point precision allowed the workstations to execute the workflow in less time and also reduced memory usage dramatically. For all three AI workflows we executed, we consider the time the workstations needed to complete the tasks to be acceptable, and believe that these workstations can be appropriate, cost-effective choices for these kinds of activities.

Compared to a cluster of PowerEdge R750 servers running VMware Cloud Foundation 4.5
Conclusion
If your company is struggling with underperforming infrastructure, upgrading to 16th Generation Dell PowerEdge servers running VCF 5.1 could be just what you need to handle more database throughput and reduce vSAN latencies. We found that a Dell PowerEdge R760 server cluster running VCF 5.1 processed over 78 percent more TPM and 79 percent more NOPM than a Dell PowerEdge R750 server cluster running VCF 4.5. It’s also worth noting that the PowerEdge R750 cluster bottlenecked on vSAN storage, with max write latency at 8.9ms. For reference, the PowerEdge R760 cluster clocked in at 3.8ms max write latency. This higher latency is due in part to the single disk group per host on the moderately configured PowerEdge R750 cluster, while the better-configured PowerEdge R760 cluster supported four disk groups per host. As an additional benefit to IT admins, we also found that the embedded VMware Aria Operation adapter provided useful infrastructure insights.

Comparing Java performance: Red Hat Enterprise Linux 6 and OpenJDK vs. Microsoft Windows Server 2012 and Oracle Java HotSpot
1. APRIL 2013
A PRINCIPLED TECHNOLOGIES TEST REPORT
Commissioned by Red Hat, Inc.
COMPARING JAVA PERFORMANCE: RED HAT ENTERPRISE LINUX 6 AND OPENJDK
VS. MICROSOFT WINDOWS SERVER 2012 AND ORACLE JAVA HOTSPOT
Java language comes with an attractive promise of “write once, run anywhere,”
implying that the application code needs to be compiled only once. While “write once”
is largely true, the challenges associated with “run anywhere” often leave users
wondering what other factors they should be considering while selecting their next Java
application platform.
Java Virtual Machine (JVM) provides a sufficiently rich abstraction layer to run
applications independent of particular computer hardware implementation. However,
JVMs typically do not run directly on hardware platforms and require an operating
system (OS) to interact with the underlying hardware resources. That makes selection of
the OS, along with hardware architecture and JVM implementation, an important step
in defining any Java application platform.
To help you make this assessment, we used the SPECjbb20131
benchmark in the
Principled Technologies labs, to compare the Java performance of two popular
operating system and JVM implementations: Red Hat Enterprise Linux 6 with OpenJDK2
(Red Hat/OpenJDK solution) and Microsoft Windows Server 2012 with Oracle Java
HotSpot (Microsoft/Java HotSpot solution). To minimize differences in the hardware
configuration and setup, we used the same server hardware to perform both tests.
We found that Red Hat Enterprise Linux 6 with OpenJDK outperformed
Windows Server 2012 with Java Hotspot, achieving up to 1.7 percent more critical-jOPS

2. A Principled Technologies test report 2Comparing Java performance: Red Hat Enterprise Linux 6 and OpenJDK
vs. Microsoft Windows Server 2012 and Oracle Java HotSpot
and 3.7 percent more max-jOPS using small heap settings.3
Moreover, using a large heap
size, the Red Hat/OpenJDK solution scored 22,126 critical-jOPS and 34,129 max-jOPS,
while Windows Server 2012 and the Java HotSpot JVM did not report a qualifying result
on the SPECjbb2013 benchmark when using a large heap.4
BETTER SPECJBB2013 PERFORMANCE
The operating system and the JVM that are being deployed on your servers can
directly affect the performance your applications deliver. For our comparison of Red Hat
Enterprise Linux 6 with OpenJDK and Microsoft Windows Server 2012 with Java
HotSpot, we used the SPECjbb2013 benchmark with both large and small heap settings.
For detailed system configuration information, see Appendix A. See Appendix B for step-
by-step testing details.
Figure 1 shows the scores that the systems achieved on the SPECjbb2013
benchmark with both large heap and small Java heap settings. When the Java program
starts, the JVM requests a memory block from the OS and allocates it to that
application. That block of memory is consecutively called Java heap and is managed by
JVM.
We used a 240GB heap size for the Red Hat/OpenJDK solution in the large heap
scenario and a 20GB heap size in the small heap scenario. When using a 240GB heap
size with the Microsoft/Java HotSpot solution, the benchmark failed to run. We then
used a similar large heap (232GB) configuration, and the benchmark ran but did not
report a qualifying score.

Small heap (20GB) OpenJDK and Java HotSpot JVM results were not submitted to SPEC for publication.

This result is an officially submitted SPECjbb2013 result at spec.org. See http://www.spec.org/jbb2013/results/res2013q2/jbb2013-
