Benchmarking the Cloud [34764]
By Brendan Gregg

Brendan Gregg writes, "Benchmarking, and benchmarking the cloud, is incredibly error prone. I provided guidance though this minefield in the benchmarking chapter of my book (Systems Performance: Enterprise and the Cloud); that chapter can be read online on the InformIT site. I also gave a lightning talk about benchmarking gone wrong at Surge last year. In this post, I'm going to cut to the chase and show you the tools I commonly use for basic cloud benchmarking..."

SPARC T5-2 Delivers World Record 2-Socket Application Server [34573]
for SPECjEnterprise2010 Benchmark

Oracle's SPARC T5-2 servers have set the world record for the SPECjEnterprise2010 benchmark using two-socket application servers with a result of 17,033.54 SPECjEnterprise2010 EjOPS. The result used two SPARC T5-2 servers, one server for the application tier and the other server for the database tier.

The SPARC T5-2 server delivered 29% more performance compared to the 2-socket IBM PowerLinux server result of 13,161.07 SPECjEnterprise2010 EjOPS.

The two SPARC T5-2 servers have 1.2x better price performance than the two IBM PowerLinux 7R2 POWER7+ processor-based servers (based on hardware plus software configuration costs for both tiers). The price performance of the SPARC T5-2 server is $35.99 compared to the IBM PowerLinux 7R2 at $44.75.

The SPARC T5-2 server demonstrated 1.5x more performance compared to Oracle's x86-based 2-socket Sun Server X4-2 system (Ivy Bridge) result of 11,259.88 SPECjEnterprise2010 EjOPS. Oracle holds the top x86 2-socket application server SPECjEnterprise2010 result.

This SPARC T5-2 server result represents the best performance per socket for a single system in the application tier of 8,516.77 SPECjEnterprise2010 EjOPS per socket.

The application server used Oracle Fusion Middleware components including the Oracle WebLogic 12.1 application server and Java HotSpot(TM) 64-Bit Server VM on Solaris, version 1.7.0_45. The database server was configured with Oracle Database 12c Release 1.

This result demonstrated less than 1 second average response times for all SPECjEnterprise2010 transactions and represents Jave EE 5.0 transactions generated by 139,000 users.

Performance Analysis in a Multitenant Cloud Environment [34119]
By Orgad Kimchi

Orgad Kimchi writes, "Analyzing the performance of a virtualized multitenant cloud environment can be challenging because of the layers of abstraction. This article shows how to use Oracle Solaris 11 to overcome those limitations..."

World Record Single System TPC-H @10000GB Benchmark on SPARC T5-4 [33807]
4-chip SPARC T5-4 server is significantly faster than the 8-chip server results from HP

Oracle's SPARC T5-4 server delivered world record single server performance of 377,594 QphH@10000GB with price/performance of $4.65/QphH@10000GB USD on the TPC-H @10000GB benchmark. This result shows that the 4-chip SPARC T5-4 server is significantly faster than the 8-chip server results from HP (Intel x86 based).

  • The SPARC T5-4 server with four SPARC T5 processors is 2.4 times faster than the HP ProLiant DL980 G7 server with eight x86 processors.

  • The SPARC T5-4 server delivered 4.8 times better performance per chip and 3.0 times better performance per core than the HP ProLiant DL980 G7 server.

  • The SPARC T5-4 server has 28% better price/performance than the HP ProLiant DL980 G7 server (for the price/QphH metric).

  • The SPARC T5-4 server with 2 TB memory is 2.4 times faster than the HP ProLiant DL980 G7 server with 4 TB memory (for the composite metric).

  • The SPARC T5-4 server took 9 hours, 37 minutes, 54 seconds for data loading while the HP ProLiant DL980 G7 server took 8.3 times longer.

  • The SPARC T5-4 server accomplished the refresh function in around a minute, the HP ProLiant DL980 G7 server took up to 7.1 times longer to do the same function.

This result demonstrates a complete data warehouse solution that shows the performance both of individual and concurrent query processing streams, faster loading, and refresh of the data during business operations. The SPARC T5-4 server delivers superior performance and cost efficiency when compared to the HP result.

Optimizing OS performance [33633]
With Ops Center's OS Analytics tools

Owen Allen writes, "With the right information, there's a lot that you can do to improve the performance of an operating system. However, it can be time-consuming to gather that information in a large environment with hundreds or thousands of operating systems, Oracle Solaris Zones, or Oracle VM Servers.

Ops Center's OS Analytics tools can help you gather the information that you need to tune your operating systems. For operating systems managed by Ops Center, you can view OS performance info like CPU and memory utilization, process details, and virtualization capacity. For Oracle Solaris systems, you can also view the status and details of SMF services.

We put together a "how-to" that walks you through the process of viewing all of this information..."

Open Source Systems Performance [33537]
Video and Slides of Brendon's OSCON Talk

Brendan writes, "There is an important and untold story about open source and systems performance, which I'm uniquely positioned to tell. I presented it at OSCON earlier this year, which was the perfect venue. My talk, Open Source Systems Performance, was a play in three acts:

  • Act 1. Before Open Source
  • Act 2. Open Source
  • Act 3. Closed Source

Linux appears in Act 2, but this story can only really be told by the Solaris operating system. Solaris was closed, then opened, and then closed again, providing acute examples of the value that an open source operating system provides for systems performance..."
