MarkLogic Linux Tuned Profile


The tuned tuning service can change operating system settings to improve performance for certain workloads. Different tuned profiles are available and choosing the profile that best fits your use case simplifies configuration management and system administration. You can also write your own profiles, or extend the existing profiles if further customization is needed. The tuned-adm command allows users to switch between different profiles.

RedHat Performance and Tuning Guide: tuned and tuned-adm

  • tuned-adm list will list the available profiles
  • tuned-adm active will list the active profile

Creating a MarkLogic Tuned Profile

Using the throughput-performance profile, we can create a custom tuned profile for MarkLogic Server. First create the directory for the MarkLogic profile:

sudo mkdir /usr/lib/tuned/MarkLogic/

Next, create the tuned.conf file that will include the throughput-performance profile, along with our recommended configuration:

# tuned configuration

summary=Optimize for MarkLogic Server on Bare Metal

vm.swappiness = 1
vm.dirty_ratio = 40


Activating the MarkLogic Tuned Profile

Now when we do a tuned list it should show us the default profiles, as well as our new MarkLogic profile:

$ tuned-adm list
Available profiles:
- MarkLogic                   - Optimize for MarkLogic Server
- balanced                    - General non-specialized tuned profile
- desktop                     - Optimize for the desktop use-case
- hpc-compute                 - Optimize for HPC compute workloads
- latency-performance         - Optimize for deterministic performance at the cost of increased power consumption
- network-latency             - Optimize for deterministic performance at the cost of increased power consumption, focused on low latency network performance
- network-throughput          - Optimize for streaming network throughput, generally only necessary on older CPUs or 40G+ networks
- powersave                   - Optimize for low power consumption
- throughput-performance      - Broadly applicable tuning that provides excellent performance across a variety of common server workloads
- virtual-guest               - Optimize for running inside a virtual guest
- virtual-host                - Optimize for running KVM guests
Current active profile: virtual-guest

Now we can make MarkLogic the active profile:

$ sudo tuned-adm profile MarkLogic

And then check the active profile:

$ tuned-adm active
Current active profile: MarkLogic

Disabling the Tuned Daemon

The tuned daemon does have some overhead, and so MarkLogic recommends that it be disabled. When the daemon is disabled, tuned will only apply the profile settings and then exit. Update the /etc/tuned/tuned-main.conf and set the following value:

daemon = 0
