---+++ !ModPerl Setup (high load)

*Description:* 
   * Evaluated response times of resolver using *ab* (ApacheBench)
   * This setup is using plain CGI. Major improvements are expected if mod_perl is used instead (50% gain, at least).
   * Total Requests: 1000
   * Concurrency: 25
   * Requests per second:     60.24 [#/sec] (mean)
   * Time per request:        415.016 [ms] (mean)

*Command:*

<pre>ab -n 100 -c 10 http://tdwgbox.tdwg.gbif.org/authority/metadata/?lsid=urn:lsid:lsid.tdwg.gbif.org:standards:64</pre>

*Output:*
