Cvs log & CvsChangeLog are painfully slow

           Summary: Cvs log & CvsChangeLog are painfully slow
           Product: Ant
           Version: 1.5.3
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Core tasks
        AssignedTo: dev@ant.apache.org
        ReportedBy: peter@leschev.com


The following issue is described well in the following email:
http://marc.theaimsgroup.com/?l=ant-user&m=103652443632318&w=2

When running cvs log through the Cvs task & cvsChangeLog task, the time taken to
process these requests are painfully slow compared to calling cvs log > aFile.

Using the build file below, Cvs log & cvsChangeLog takes 50 seconds on a fairly
small project. When running "cvs log > temp.txt" from a shell, it takes around 2
seconds. On bigger projects, running through ant takes 5mins for both cvs log &
cvsChangeLog, while running from the shell script, it takes around 20seconds.

Note: /nfs/based/root = the NFS location of the CVS Repository.
