Hello Ampere Developers,
What do you look for in a build server?
One of the most common uses of Ampere servers is as build nodes for software being built, tested, and packaged for Arm64. What do you look for in a build server, and how can you tweak your server to make it faster?
That’s what we explore this month in a Tuning Guide on build server configuration: Optimizing Arm-based build servers with AmpereOne CPUs
Skipping straight to the recommendations, we come up with four things that are most important for efficient use of a build server:
-
First, build servers can take advantage of more cores, by compiling different source files in parallel.
-
Configuring your CPUs to run in “performance” mode with the p-governor can reduce the time spent in power management, which increased raw compilation speed by 17% on our reference workload
-
By slowing down the heartbeat of the kernel, you can reduce kernel interrupts and context switches, which can increase performance by another few percentage points
-
Finally, project builds typically include both serial steps like configuration and linking, and parallelizable steps. To keep your build server busy, you can send new build tasks to the server regularly – with parallelizable phases running at the same time as those that only keep one core busy, you improve the overall throughput of your build node.

The Case for Ceph on Arm64, with IBM’s Federico Lucifredi
On July 1st 2026, at noon PDT/3pm EDT/9pm CEST, Federico Lucifredi, Product Management Director for the Ceph Platform at IBM and Red Hat, joins Ampere’s Dave Neary for a deep dive into Ceph’s move to bring commercial support to Ceph on Arm64. Ceph has been a powerhouse in the open-source storage world for years, and in the past 12 months there have been a number of key breakthroughs in commercial support of both the Ceph client libraries and Ceph clusters on Arm64. Federico and Dave will explore the journey to commercial support of Ceph on Arm64, and why Ceph users should consider running their next cluster on Arm64.
