Content groupsAccelerator for WordPress

It is a list of content groups allowing changing common settings and setting self-learning parameters depend on specified content’s scope. When groups are applied to particular page the first scope match will be chosen. Also, scopes matches independently for each mode.

Each group element contains settings described below.

Modes#

Each enabled mode will apply the related settings below.

• Common settings’ overriding

  Allows to set optimization settings that different from common ones. E.g. scripts loading delay can be set for to lower value for desktop only.

• Self-learning

  Enables self-learning technology while optimization that increases its speed.

Name#

Optional group’s name for simplify identification.

Scope#

Actually, it is a filter to pages that will be included in particular group. Each of next filter is applied by logical ‘and’.

• URI paths

  Only matched pages’ URLs will be included. An empty list means all pages. The syntax is the same as in URI paths exclusions.

• Content’s patterns

  Only pages that contain specified parts via their XPaths will be included. An empty list means any parts.

• Views

  Only selected devices’ views will be included. If no views are selected it means all views.

Common settings’ overrides#

• Enable content optimization

  If disabled then no optimization will be made including below styles and scripts.

• Scripts

  Enables overriding some of scripts settings.

• Styles

  Enables overriding some of styles settings.

Self-learning#

It enables self-learning technology while optimization that generates specific optimization’s data for particular page structure and uses it in optimizations of other pages with the same structure.

• Fast processing

  Significantly increases a speed of optimization but can produce larger (up to about 20%) critical styles files.

• Exclusions for pages’ structure comparing

  Specifies pages’ elements that won’t be included in page structure. E.g. by default, style, link, head tags are already excluded.

• Exclusions for pages’ styles selector comparing

  Specifies regular expression masks for omitting styles’ selectors parts. If particular expression contains regular expression’s catch group the only it will be omitted. E.g. for style selector .class-1.class-2.class-3 expression @\.class-2@ will transform it to .class-1.class-3 but expression @\.class-(2)@ will transform it to .class-1.class-.class-3.

Debugging#

While tuning up similar pages for self-learning it can be useful to check page’s structure. If debug mode is enabled and enter additional parameter to the URL seraph_accel_proc=LRNSTR (e.g. https://my-site.com/?seraph_accel_proc=LRNSTR) then there will be <script type="text/seraph-accel-learnComparingStructure"> element in page’s DOM under head tag with a structure.
