Hi All, Thanks for reading the post. In one of my java classes I am using Sun FTP service through FtpClient as well as Apache's FTPClient. While retrieving the files from the FTP server for some reason on WebSphere the CPU usage goes to 50%(which is = 100% as the unix box has got dual CPU). If I run the same class on the Tomcat the CPu usage will not go much. Anyone is aware of this kind of behaviour on WebSphere? Please advise me if there is any tuning techneque around FTP. Thanks, Gautham.
