ZVM with ZST Installation Prerequisites Details
| Note |
These prerequisites are only applicable to the Zing Virtual Machine (ZVM) running in the ZST mode. |
While ZVM with ZST run fine with certain default system settings, there are default OS settings that can cause response time sensitive applications to experience multi-hundred-of-millisecond stalls regardless of the JVM. Since Zing tends to eliminate or dramatically reduce JVM-related stalls, these remaining OS related stalls will tend to dominate the worst-case latency behavior of applications. It is therefore highly recommended that the following settings be applied.
To ensure that OS settings are appropriate for performance sensitive applications, apply the following settings.
If you are using a Nehalem power efficiency chip set in the latency-sensitive systems, you might need to disable the Intel idle driver.
