    Performance issue with file system connector

    Neil Zou Newbie

      Hi all,

       

      I'm using modeshape 2.8.1.Final, and I'm trying to upload 5000 xml files to a empty file system repository. The processing time for each file increases from 0.4 seconds to 4.5 seconds.

       

      Below is my configuration:

       

      <?xml version="1.0" encoding="UTF-8"?>

      <configuration xmlns:mode="http://www.modeshape.org/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0">

       

          <mode:sources jcr:primaryType="nt:unstructured">

       

              <mode:source jcr:name="pocFS" mode:classname="org.modeshape.connector.filesystem.FileSystemSource"

                  mode:workspaceRootPath="/dev/poc/workspaces"

                  mode:defaultWorkspaceName="poc"

                  mode:creatingWorkspacesAllowed="false"

                  mode:updatesAllowed="true">

       

                  <mode:cachePolicy jcr:name="nodeCachePolicy"

                      mode:classname="org.modeshape.graph.connector.base.cache.InMemoryNodeCache$PathCachePolicy"

                      mode:timeToLive="300" />

       

              </mode:source>

          </mode:sources>

       

          <mode:mimeTypeDetectors>

              <mode:mimeTypeDetector jcr:name="Detector">

                  <mode:description>Standard extension-based MIME type detector</mode:description>

                  <mode:classname>org.modeshape.graph.mimetype.ExtensionBasedMimeTypeDetector</mode:classname>

              </mode:mimeTypeDetector>

          </mode:mimeTypeDetectors>

       

          <mode:repositories>

       

              <mode:repository jcr:name="pocFileRepo">

                  <mode:source>pocFS</mode:source>

                  <mode:options jcr:primaryType="mode:options">

                      <jaasLoginConfigName jcr:primaryType="mode:option" mode:value="modeshape-jcr"/>

                      <queryIndexDirectory jcr:primaryType="mode:option" mode:value="/dev/poc/workspaceindex" />

                  </mode:options>

                  <mode:nodeTypes jcr:primaryType="mode:nodeTypes"/>

                  <namespaces jcr:primaryType="mode:namespaces" />

              </mode:repository>

       

          </mode:repositories>

      </configuration>

       

       

      Files in workspacetime taken for each file
      00.4
      10001.1
      20001.9
      41003.6
      48004.4

       

      I found the bottleneck is in below two methods, each taken around 2 seconds.

      PathTransaction.getChildren(..)

      RequestProcessor.process( ReadBranchRequest request)

       

      Could anyone give me a hint to improve performance in this case?

       

      Thanks
