+
+== Overview ==
+
+This RFC improves performance by getting batch layers in one request, instead of each layer in one request.
+
+== Motivation ==
+
+Currently MgMap is created on Web Extension side, and for each layer of this map it sends a request to get the resource content. This causes a lot of requests send to server again and again. To improve performance MgMap should get the layers in a single request, and use the batch processing result to create layer models. The more layers a map has, the better performance improvement is achieved.
+
+== Proposed Solution ==
+
+The possible solutions could be:[[BR]]
+1.      Add a new API of ResourceService to get a batch of resource contents for a collection of resource identifiers[[BR]]
+
+{{{
+INTERNAL_API:
+    ///////////////////////////////////////////////////////////////////////////
+    /// \brief
+    /// Gets the contents of the specified resources.
+    ///
+    /// \param resources
+    /// Resource identifiers describing the resources.
+    /// \param preProcessTags
+    /// Pre-processing to apply to resource before returning content.  An empty
+    /// string indicate no pre-processing. See MgResourcePreProcessingType for
+    /// a list of supported pre-processing tags.
+    ///
+    /// \return
+    /// MgStringCollection object representing the corresponding resource contents.
+    ///
+    /// \exception MgInvalidRepositoryTypeException
+    /// \exception MgInvalidRepositoryNameException
+    /// \exception MgInvalidResourcePathException
+    /// \exception MgInvalidResourceNameException
+    /// \exception MgInvalidResourceTypeException
+    ///
+    virtual MgStringCollection* GetResourceContent(MgStringCollection* resources,
+        MgStringCollection* preProcessTags) = 0;
+}}}
+[[BR]]
+
+2.      MgMap doesn't request the resource content of layers one by one, instead it forms a collection of layer resource ids, and use the new API to get a collection of layer definitions.
