POWER Is Not Just for Databases
The IBM POWER architecture is not just for database servers. While most people know it only for DB2 and SAP HANA, it is an ideal platform also for HPC or other high performance server applications, like syslog-ng.
While all the buzz is around POWER 11 now, we have yet to see real-world testing results, as GA is still a few weeks away. You can learn more about POWER 11 at https://newsroom.ibm.com/2025-07-08-ibm-power11-raises-the-bar-for-enterprise-it. I am an environmental engineer by degree, so, my favorite part is: “Power11 offers twice the performance per watt versus comparable x86 servers”.
People look surprised when I mention that I am an IBM Champion for POWER, saying “You are not a database guy. What do you have to do with POWER?”. Well, I have 30+ years of history with POWER, but I never had to do anything with databases. My focus was always open source software, even on AIX: https://opensource.com/article/20/10/power-architecture
Of course, we should not forget that POWER is the best platform to run SAP HANA workloads. Not just locally, but also in the cloud: https://www.ibm.com/new/announcements/ibm-and-sap-launch-new-hyperscaler-option-for-sap-cloud-erp. However, there are many other use cases for POWER.
I must admit that I’m not really into chip design. Still, it fascinates me how IBM POWER is more powerful (pun intended!), when it comes to a crucial part: Physical Design Verification using Synopsys IC Validator (ICV). While most people complain that POWER hardware is expensive, it is also faster. Compared to x86, it still can provide a 66% better TCO on workloads like PDV.

Do you still think that buying hardware is too expensive? You can try PowerVS, where POWER 11 will also be available soon: https://community.ibm.com/community/user/blogs/anthony-ciccone/2025/07/07/ibm-power11-launches-in-ibm-power-virtual-server-u
Obviously, my favorite part is a simple system utility: syslog-ng. It is an enhanced logging daemon with a focus on portability and high-performance central log collection. When POWER 9 was released, I did a few performance tests. On the fastest x86 servers I had access to, syslog-ng barely could reach collecting 1 million messages a second. The P9 server I had access to could collect slightly more than 3 million, which is a significant difference. Of course, testing results not only depend on the CPU, but also on OS version, OS tuning, side-channel attack mitigation, etc.
I am not sure when I’ll have access to a POWER 11 box. However, you can easily do syslog-ng performance tests yourself using a shell script: https://github.com/czanik/sngbench/ Let me know if you have tested it out on P11! :-)
