Bulk Item Publishing Performance

Any modern server has multi core processors. Publishing bulk items will always be quite slow, there is a lot of reading, writing and indexing that is required. Now how simply can improve performance.

Don’t forget to use Publishing.MaxDegreeOfParallelism setting.This will be dramatically improved your publishing performance.

Add patch file to update this entry.

<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
  <sitecore>
    <settings>
      <!-- This setting is changed from the default value to enable parallel processing of publishing candidates.
           The value '3' is specified here as an example.
           The optimal value for this setting depends on your solution and on the CPU capacity of the server that runs the publishing operations.

           For example, if the system architecture leverages a dedicated publishing instance with plenty of CPU capacity, this setting can be
           increased even further.
           On the other hand, on solutions where publishing is run on an authoring server that is already running a high load, changing this
           setting to a non-default value may cause system stability issues. 
           We highly recommend that you perform publishing tests with the expected load before you change this setting in production environments.

           Please remember that your database server's CPU and disk capacity may need to be adjusted to accommodate this setting.
