We have Red Hat Enterprise Linux (RHEL) 5.5 with Advanced Platform version on our server. Windows sources system (SRC1) , has Windows Server 2003 on their server that hosts Cygwin. They recently moved from FTP to SFTP. They are using Cygwin to support SFTP on Windows. The Cygwin setup version is 2.738. During sFTP load testing with SRC1, we encountered significant performance issue. Transferring 120K files of total size 58GB takes 4.5 hours using FTP but it takes 28 hours using SFTP. We have not encountered any performance problems with downloading files (same number and size ) from unix/linux systems using SFTP. We suspect this performance issue to be related to Cygwin. Any inputs on this is greatly appreciated. -- View this message in context: http://old.nabble.com/Performance-issue-in-SFTP-%2C-CygWin-Server-tp32595286p32595286.html Sent from the Cygwin list mailing list archive at Nabble.com. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
