title: Ant copy task slower on 11.04 than 10.04
body: <p>We use ant as part of our build system for copying a load of various files around, on 10.04 the entire process takes ~5 minutes, however as we've now started to shift onto 11.04 as our primary development platform we've noticed that it now takes ~25 minutes which is a fairly large factor to increase. </p>
  
  <p>Has anyone noticed anything similar or have we just got some strange issue?</p>
  
  <p>EDIT: <a href="https://gist.github.com/2049693" rel="nofollow">https://gist.github.com/2049693</a> a gist of a 2 minute overview of vmstat running whilst a very heavy ant copy task runs. </p>
  
  <p>EDIT: More info, both 10.04 and 11.04 run Java 1.6, Ant version on 10.04 is 1.7.1, Ant version on 11.04 is 1.8.0 (both installed from Ubuntu main repo's). Executing one of our biggest copy processes is actually <em>visibly</em> slower when run with verbose on. </p>
  
  <p>EDIT: Issue occurs with the latest version of ant (1.8.3) installed both from binary and from source. </p>
