-------------------------------+---------------------
 The following '''untested''' change to `/etc/tomcat6/server.xml` should
 turn on compression for JSON responses starting at 2KiB.  (I took the
 opportunity to also changes "metrics" to "onionoo" in two places.)

 {{{
                 maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
                 enableLookups="false" redirectPort="8443"
 acceptCount="100"
                 connectionTimeout="20000" disableUploadTimeout="true"
 -               compression="off" compressionMinSize="2048"
 +               compression="on" compressionMinSize="2048"
                 noCompressionUserAgents="gozilla, traviata"
 -               compressableMimeType="text/html,text/xml,text/plain" />
 +               compressableMimeType="application/json" />
      <Engine name="Catalina" defaultHost="sewerzowi.torproject.org">
 -      <Host name="metrics.torproject.org" appBase="webapps"
 +      <Host name="onionoo.torproject.org" appBase="webapps"
              unpackWARs="true" autoDeploy="true"
              xmlValidation="false" xmlNamespaceAware="false">
          <Alias>sewerzowi.torproject.org</Alias>
          <Valve className="org.apache.catalina.valves.AccessLogValve"
 -               directory="logs" prefix="metrics_access_log."
 suffix=".txt"
 +               directory="logs" prefix="onionoo_access_log."
 suffix=".txt"
                 pattern="%l %u %t %r %s %b" resolveHosts="false"/>
        </Host>
      </Engine>
 }}}

 If It's easier to compress responses in Apache, not in Tomcat, that's fine
 by me, too.
