+Tuning Ironic
+=============
+
+Memory Utilization
+==================
+
+Memory utilization is a difficult thing to tune in Ironic as largely we may
+be asked by API consumers to perform work for which the underlying tools
+require large amounts of memory.
+
+The biggest example of this is image conversion. Images not in a raw format
+need to be written out to disk (local files or remote in iscsi deploy) which
+requires the conversion process to generate an in-memory map to re-assemble
+the image contents into a coherent stream of data. This entire process also
+stresses the kernel buffers and cache.
+
+This ultimately comes down to a trade-off of Memory versus Performance,
+similar to the trade-off of Performance versus Cost.
+
+On a plus side, an idle Ironic deployment does not need much in the way
+of memory. On the down side, a highly bursty environment where a large
+number of concurrent deployments may be requested should consider two
+aspects:
+
+* How is the ironic-api service/process set up? Will more
+  processes be launched automatically?
+* Are images prioritized for storage size on disk? Or are they compressed and
+  require format conversion?
+
+API
+===
+
+Ironic's API should have a fairly stable memory footprint with activity,
+however depending on how the webserver is running the API, additional
+processes can be launched.
+
+Under normal conditions, as of Ironic 15.1, the ``ironic-api`` service/process
+consumes approximately 270MB of memory per worker. Depending on how the
+process is being launched, the number of workers and maximum request threads
+per worker may differ. Naturally there are configuration and performance
+trade-offs.
+
+* Directly as a native python process, i.e. execute ``ironic-api``
+  processes. Each single worker allows for multiple requests to be handled
+  and threaded at the same time which can allow high levels of request
+  concurrency. As of the Victoria cycle, a direct invocation of the
+  ``ironic-api`` program will only launch a maximum of four workers.
+* Launched via a wrapper such as Apache+uWSGI may allow for multiple distinct
+  worker processes, but these workers typically limit the number of request
+  processing threads that are permitted to execute. This means requests can
+  stack up in the front-end webserver and be released to the ``ironic-api``
+  as prior requests complete. In environments with long running synchronous
+  calls, such as use of the vendor passthru interface, this can be very
+  problematic.
+
+When the webserver is launched by the API process directly, the default is
+based upon the number of CPU sockets in your machine.
+
+When launching using uwsgi, this will entirely vary upon your configuration,
+but balancing workers/threads based upon your load and needs is highly
+advisable. Each worker process is unique and consumes far more memory than
+a comparable number of worker threads. At the same time, the scheduler will
+focus on worker processes as the threads are greenthreads.
+
+.. note::
+   Host operating systems featuring in-memory de-duplication should see
+   an improvement in the overall memory footprint with multiple processes,
+   but this is not something the development team has measured and will vary
+   based upon multiple factors.
+
+One important item to note: each Ironic API service/process *does* keep a
+copy of the hash ring as generated from the database *in-memory*. This is
+done to help allocate load across a cluster in-line with how individual nodes
+and their responsible conductors are allocated across the cluster.
+In other words, your amount of memory WILL increase corresponding to
+the number of nodes managed by each ironic conductor. It is important
+to understand that features such as `conductor groups <./conductor-groups.rst>`_
+means that only matching portions of nodes will be considered for the
+hash ring if needed.
+
+Conductor
+=========
+
+A conductor process will launch a number of other processes, as required,
+in order to complete the requested work. Ultimately this means it can quickly
+consume large amounts of memory because it was asked to complete a substantial
+amount of work all at once.
+
+The ``ironic-conductor`` from ironic 15.1 consumes by default about 340MB of
+RAM in an idle configuration. This process, by default, operates as a single
+process. Additional processes can be launched, but they must have unique
+resolvable hostnames and addresses for JSON-RPC or use a central
+oslo.messaging supported message bus in order for Webserver API to Conductor
+API communication to be functional.
+
+Typically, the most memory intensive operation that can be triggered is a
+image conversion for deployment, which is limited to 1GB of RAM per conversion
+process.
+
+Most deployments, by default, do have a concurrency limit depending on their
+Compute (See `nova.conf <https://docs.openstack.org/nova/latest/configuration/sample-config.html>`_
+setting ``max_concurrent_builds``) configuration. However, this is only per
+``nova-compute`` worker, so naturally this concurrency will scale with
+additional workers.
+
+Stand-alone users can easily request deployments exceeding the Compute service
+default maximum concurrent builds. As such, if your environment is used this
+way, you may wish to carefully consider your deployment architecture.
+
+With a single nova-compute process talking to a single conductor, asked to
+perform ten concurrent deployments of images requiring conversion, the memory
+needed may exceed 10GB. This does however, entirely depend upon image block
+structure and layout, and what deploy interface is being used.
+
+What can I do?
+==============
+
+Previously in this document, we've already suggested some architectural
+constraints and limitations, but there are some things that can be done
+to maximize performance. Again, this will vary greatly depending on your
+use.
+
+* Use the ``direct`` deploy interface. This offloads any final image
+  conversion to the host running the ``ironic-python-agent``. Additionally,
+  if Swift or other object storage such as RadosGW is used, downloads can
+  be completely separated from the host running the ``ironic-conductor``.
+* Use small/compact "raw" images. Qcow2 files are generally compressed
+  and require substantial amounts of memory to decompress and stream.
+* Tune the internal memory limit for the conductor using the
+  ``[DEFAULT]memory_required_minimum`` setting. This will help the conductor
+  throttle back memory intensive operations. The default should prevent
+  Out-of-Memory operations, but under extreme memory pressure this may
+  still be sub-optimal. Before changing this setting, it is highly advised
+  to consult with your resident "Unix wizard" or even the Ironic
+  development team in upstream IRC. This feature was added in the Wallaby
+  development cycle.
+* If network bandwidth is the problem you are seeking to solve for, you may
+  wish to explore a mix of the ``direct`` deploy interface and caching
+  proxies. Such a configuration can be highly beneficial in wide area
+  deployments. See :ref:`Using proxies for image download <ipa-proxies>`.
